Secure Shell (SSH) Version 2 server support in k2 images

By default, the k2 images support both SSHv1 connections and SSHv2 connections. To restrict connections to either SSHv1 or SSHv2, enter the ip ssh mode [v1 | v2] global configuration mode command. Except for the v1 and v2 keywords for the ip ssh mode command, you configure SSHv2 the same as SSHv1. Refer to this publication for more information:

http://www.cisco.com/en/US/docs/ios/12_1t/12_1t1/feature/guide/sshv1.html

For information about SSHv1 client support, refer to the following publication:

The ip wccp service redirect in interface command is supported in software on the MSFC2. Refer to the following publication for more information:

http://www.cisco.com/en/US/docs/ios/12_1/12_1e13/feature/guide/e_wccpi.html

The standby delay minimum reload interface command configures the delay period before the initialization of Hot Standby Routing Protocol (HSRP) groups. Use the no form of this command to disable the delay period. The syntax of the command is as follows:

standby delay minimum [min_delay] reload [reload_delay]
no standby delay minimum [min_delay] reload [reload_delay]

The variable parameters are as follows:

min_delay—(Optional) Minimum time (in seconds) to delay HSRP group initialization after an interface comes up. This minimum delay period applies to all subsequent interface events.

reload_delay—(Optional) Time (in seconds) to delay after the router has reloaded. This delay period applies only to the first interface-up event after the router has reloaded.

The default minimum delay is 1 second; the default reload delay is 5 seconds.

If the active router fails or is removed from the network, the standby router automatically becomes the new active router. If the former active router comes back online, you can control whether it takes over as the active router by using the standby preempt command.

Even if you do not enter the standby preempt command, the former active router resumes the active role after it reloads and comes back online. Use the standby delay minimum reload command to set a delay period for HSRP group initialization. This command allows time for the packets to get through before the router resumes the active role.

We recommend that you use the standby delay minimum reload command if the standby timers command is configured in milliseconds or if HSRP is configured on a VLAN interface of a switch.

In most configurations, the default values provide sufficient time for the packets to get through, and you do not need to configure longer delay values.

The delay is canceled if an HSRP packet is received on an interface.

New commands for Protocol Independent Multicast (PIM) scalability and convergence enhancements:

[no] ip multicast rpf interval command

[no] ip multicast rpf triggered {min | max} command

With this command, you can change the periodic polling of the routing tables so that PIM joins are triggered only when there are changes in the routing tables.

With a PFC2 and Catalyst software release 7.2(1) or later on the Supervisor Engine 2, hardware support for policy-based routing (PBR) route-map sequences that use the set ip default next-hop keywords.

Support for RADIUS load balancing and Virtual Private Networking (VPN) load balancing.

Single router mode (SRM) enhancement—You can specify the transition time that the newly designated MSFC waits before it downloads the new Layer 3 switching information to the supervisor engine.

If the MSFC address falls within the range of a PBR ACL, traffic addressed to the MSFC is policy routed in hardware instead of being forwarded to the MSFC. To prevent policy routing of traffic addressed to the MSFC, configure PBR ACLs to deny traffic addressed to the MSFC. (CSCse86399)

http://www.cisco.com/en/US/docs/ios/12_2/ip/configuration/guide/1cfssm.html

The highest value for the maximum-paths command has been raised from six to eight.

The alt keyword is optional with the standby [group_number] ip [ip_address [secondary]] command. Without the alt keyword, the same Hot Standby Routing Protocol (HSRP) IP address and HSRP group is configured on a given interface for both MSFCs in the chassis. You can enter the alt keyword if desired. If you enter the alt keyword, you must configure the same HSRP IP address on both the designated and nondesignated MSFC.

Ethernet over MPLS—Supported only on OSM-4GE-WAN. Refer to this publication for more information:

http://www.cisco.com/en/US/docs/ios/12_1/12_1e8/feature/guide/tryvlan.html

With a PFC2, support in hardware for policy-based routing (PBR) route-map sequences that use the match ip address and set ip next-hop keywords (the MSFC2 provides processing in software for route-map sequences that use the match length and set interface keywords). Refer to the Cisco IOS Quality of Service Solutions Configuration Guide, Release 12.1, "Classification," "Configuring Policy-Based Routing," at this URL, for more information:

http://www.cisco.com/en/US/docs/ios/12_1/qos/configuration/guide/qcdpbr.html


Note With Release 12.1(11b)E and later releases on the MSFC2 and Catalyst software release 7.2(1) or later on the Supervisor Engine 2, the PFC2 provides hardware support for the set ip default next-hop PBR keywords.


Enhanced Cisco IOS Unicast RPF


Note Enhanced unicast RPF requires Catalyst software release 6.3(1) or later on the supervisor engine.


These sections describe configuring Cisco IOS unicast RPF:

Understanding Unicast RPF Support

Configuring Unicast RPF

Enabling Self-Pinging

Configuring the Unicast RPF Checking Mode

Understanding Unicast RPF Support

The Supervisor Engine 2 with PFC2 supports unicast RPF with hardware processing for packets that have a single return path. The MSFC2 processes traffic in software that has multiple return paths (for example, load sharing).

With a Supervisor Engine 2, if you configure unicast RPF to filter with an access control list (ACL), the PFC2 determines whether or not traffic matches the ACL. The PFC2 sends the traffic that matches the ACL to the MSFC2 for the unicast RPF check. The PFC2 also provides hardware support for traffic that does not match the unicast RPF ACL but that does match an input security ACL.

With Supervisor Engine 1 and PFC, the MSFC or MSFC 2 supports unicast RPF in software.

Configuring Unicast RPF

For configuration procedures, refer to the Cisco IOS Security Configuration Guide, Release 12.1, "Other Security Features," "Configuring Unicast Reverse Path Forwarding" at this URL:

http://www.cisco.com/en/US/docs/ios/12_1/security/configuration/guide/scdrpf.html

Enabling Self-Pinging

With unicast RPF enabled, the switch cannot ping itself. To enable self-pinging, perform this task:

 
Command
Purpose

Step 1 

Router(config)# interface vlan vlan_ID 

Selects the interface to configure.

Step 2 

Router(config-if)# ip verify unicast source 
reachable-via any allow-self-ping 

Enables the switch to ping itself or a secondary address.

Router(config-if)# no ip verify unicast source 
reachable-via any allow-self-ping 

Disables self-pinging.

Step 3 

Router(config-if)# exit 

Exits interface configuration mode.

This example shows how to enable self-pinging:

Router(config)# interface vlan 200
Router(config-if)# ip verify unicast source reachable-via any allow-self-ping 
Router(config-if)# end 
Router# 

Configuring the Unicast RPF Checking Mode

There are two unicast RPF checking modes:

Strict checking mode, which verifies that the source IP address exists in the FIB table and verifies that the source IP address is reachable through the input port.

Exist-only checking mode, which only verifies that the source IP address exists in the FIB table.


Note The most recently configured mode is automatically applied to all VLAN interfaces configured for unicast RPF checking.


To configure unicast RPF checking mode, perform this task:

 
Command
Purpose

Step 1 

Router(config)# interface vlan vlan_ID 

Selects an interface to configure.

Note Based on the input VLAN interface, unicast RPF verifies the best return path before forwarding the packet on to the next destination.

Step 2 

Router(config-if)# ip verify unicast source 
reachable-via {rx | any} [allow-default] [list] 

Configures the unicast RPF checking mode.

Router(config-if)# no ip verify unicast 

Reverts to the default unicast RPF checking mode.

Step 3 

Router(config-if)# exit 

Exits interface configuration mode.

When configuring the unicast RPF checking mode, note the following syntax information:

Use the rx keyword to enable strict checking mode.

Use the any keyword to enable exist-only checking mode.

Use the allow-default keyword to allow use of the default route for RPF verification.

Use the list option to identify an access list.

If the access list denies network access, spoofed packets are dropped at the port.

If the access list permits network access, spoofed packets are forwarded to the destination address. Forwarded packets are counted in the interface statistics.

When you enter the ip verify unicast source reachable-via command, the unicast RPF checking mode changes on all VLAN interfaces.

This example shows how to verify the configuration:

Router# show running-config interface vlan 200 
Building configuration...
Current configuration : 114 bytes

Cisco IOS Firewall Feature Set

These sections describe the Cisco IOS Firewall feature set on the Catalyst 6500 series switches:

Cisco IOS Firewall Feature Set Support Overview

Guidelines and Restrictions

Configuring CBAC on Catalyst 6500 Series Switches

Cisco IOS Firewall Feature Set Support Overview

The Firewall feature set images for the MSFC2 support these Cisco IOS Firewall features:

Context-based Access Control (CBAC)

Port-to-Application Mapping (PAM)

Authentication Proxy

The Firewall feature set images are c6msfc2-jo3sv-mz and c6msfc2-po3sv-mz (see the "Feature Sets" section).


Note Support for the Firewall feature set requires Catalyst software release 6.2(2) or later on the supervisor engine.


Refer to the Cisco IOS Security Configuration Guide, Release 12.1, "Traffic Filtering and Firewalls" online publications:

The "Cisco IOS Firewall Overview" chapter at this URL:

http://www.cisco.com/en/US/docs/ios/12_1/security/configuration/guide/scdfirwl.html

The "Configuring Context-Based Access Control" chapter at this URL:

http://www.cisco.com/en/US/docs/ios/12_1/security/configuration/guide/scdcbac.html

The "Configuring Authentication Proxy" chapter at this URL:

http://www.cisco.com/en/US/docs/ios/12_1/security/configuration/guide/scdauthp.html

The Cisco IOS Security Command Reference publication at this URL:

http://www.cisco.com/en/US/docs/ios/12_1/security/configuration/guide/secur_c.html

The following features are supported both with and without the use of a Cisco IOS firewall image:

Standard access lists and static extended access lists

Lock-and-key (Dynamic Access Lists)

IP session filtering (Reflexive Access Lists)

TCP intercept

Security server support

Network address translation

Neighbor router authentication

Event logging

User authentication and authorization


Note Catalyst 6500 series switches support the intrusion-detection system (IDS) module (WS-X6381-IDS). Catalyst 6500 series switches do not support the Cisco IOS Firewall IDS feature, which is configured with the ip audit command.


Guidelines and Restrictions

On other platforms, if you enter the ip inspect command on an interface, CBAC modifies access control lists (ACLs) on other interfaces to permit the inspected traffic to flow through the network device. On Catalyst 6500 series switches, you must enter the mls ip inspect command to permit traffic through any ACLs that would deny the traffic through other interfaces. See the "Configuring CBAC on Catalyst 6500 Series Switches" section.

With Supervisor Engine 2 and PFC2, reflexive ACLs and CBAC have conflicting flow mask requirements. When CBAC is configured on a switch with Supervisor Engine 2 and PFC2, reflexive ACLs are processed in software on the MSFC2.

CBAC is incompatible with VACLs. CBAC and VACLs can both be configured on the switch but not in the same subnet (VLAN).


Note The IDS module uses VACLs to select traffic. To use the IDS module in a subnet where CBAC is configured, enter the mls ip ids acl_name interface command, where acl_name is configured to select traffic for the IDS module.


Redundancy on the Catalyst 6500 series switches does not support CBAC. You can configure CBAC with high availability (HA) on the supervisor engine and Hot Standby Routing Protocol (HSRP) on the MSFC2, but no CBAC state information is preserved.

To inspect Microsoft NetMeeting (2.0 or greater) traffic, turn on both h323 inspection and tcp inspection.

To inspect web traffic, turn on tcp inspection. To avoid reduced performance, do not turn on http inspection to block Java.


Note QoS and CBAC do not interact or interfere with each other.


Configuring CBAC on Catalyst 6500 Series Switches

CBAC requires additional configuration on the Catalyst 6500 series switches.

On a network device other than a Catalyst 6500 series switch, when interfaces are configured to deny traffic, CBAC permits traffic to flow bidirectionally through the interface configured with the ip inspect command and also any other interface that the traffic must go through, as shown in this example:

Router(config)# ip inspect name permit_ftp ftp 
Router(config)# interface vlan 100 
Router(config-if)# ip inspect permit_ftp in 
Router(config-if)# ip access-group deny_ftp_a in 
Router(config-if)# ip access-group deny_ftp_b out 
Router(config-if)# exit 
Router(config)# interface vlan 200 
Router(config-if)# ip access-group deny_ftp_c in 
Router(config-if)# ip access-group deny_ftp_d out 
Router(config-if)# exit 
Router(config)# interface vlan 300 
Router(config-if)# ip access-group deny_ftp_e in 
Router(config-if)# ip access-group deny_ftp_f out 
Router(config-if)# end 

If the FTP session enters on VLAN 100 and must leave on VLAN 200, CBAC permits the FTP traffic through ACLs deny_ftp_a, deny_ftp_b, deny_ftp_c, and deny_ftp_d. If another FTP session enters on VLAN 100 and must leave on VLAN 300, CBAC permits the FTP traffic through ACLs deny_ftp_a, deny_ftp_b, deny_ftp_e, and deny_ftp_f.

On a Catalyst 6500 series switch, when interfaces are configured to deny traffic, CBAC permits traffic to flow bidirectionally only through the interface configured with the ip inspect command. You must configure other interfaces with the mls ip inspect command.

If the FTP session enters on VLAN 100 and must leave on VLAN 200, CBAC on a Catalyst 6500 series switch permits the FTP traffic only through ACLs deny_ftp_a and deny_ftp_b. To permit the traffic through ACLs deny_ftp_c and deny_ftp_d, you must enter the mls ip inspect deny_ftp_c and mls ip inspect deny_ftp_d commands, as shown in this example:

Router(config)# mls ip inspect deny_ftp_c 
Router(config)# mls ip inspect deny_ftp_d 

With the example configuration, FTP traffic cannot leave on VLAN 300 unless you enter the mls ip inspect deny_ftp_e and mls ip inspect deny_ftp_f commands.

Enter the show fm insp [detail] command to verify the configuration. The show fm insp [detail] command displays the list of ACLs and interfaces on which CBAC is configured and the status (ACTIVE or INACTIVE), as shown in this example:

Router# show fm insp 
         interface:Vlan305(in) status :ACTIVE
         acl name:deny
           interfaces:
              Vlan305(out):status ACTIVE

On VLAN 305, inspection is active in the inbound direction and there is no ACL. ACL deny is applied on VLAN 305 in the outbound direction and inspection is active.

Use the detail keyword to display all of the flow information.

If a VACL is configured on the interface before configuring CBAC, the status displayed is INACTIVE; otherwise, it is ACTIVE. If PFC resources are exhausted, the command displays BRIDGE followed by the number of failed currently active NetFlow requests that have been sent to the MSFC2 for processing.

Local Proxy ARP

WCCP Layer 2 PFC Redirection

Jumbo Frame Feature on MSFC2

Local Proxy ARP

The local proxy ARP feature allows the MSFC to respond to ARP requests for IP addresses within a subnet where normally no routing is required. With the local proxy ARP feature enabled, the MSFC responds to all ARP requests for IP addresses within the subnet and forwards all traffic between hosts in the subnet. Use this feature only on subnets where hosts are intentionally prevented from communicating directly with each other by the configuration on the switch to which they are connected.

The local proxy ARP feature is disabled by default. Use the ip local-proxy-arp interface configuration command to enable the local proxy ARP feature on an interface. Use the no ip local-proxy-arp interface configuration command to disable the feature. ICMP redirects are disabled on interfaces where the local proxy ARP feature is enabled.

To use the local proxy ARP feature, enable the IP proxy ARP feature. The IP proxy ARP feature is enabled by default. Refer to the Cisco IOS IP and IP Routing Configuration Guide, Release 12.1, "IP Addressing and Services," "Configuring IP Addressing," "Enabling Proxy ARP," at this URL:

http://www.cisco.com/en/US/docs/ios/12_1/iproute/configuration/guide/1cdipadr.html#Enabling_Proxy_ARP

WCCP Layer 2 PFC Redirection

The Cisco IOS Web Cache Communication Protocol (WCCP) Layer 2 PFC redirection feature allows directly connected Cisco Cache Engines to use Layer 2 redirection, which is more efficient than Layer 3 redirection through generic route encapsulation (GRE). You can configure a directly connected cache engine to negotiate use of the WCCP Layer 2 PFC redirection feature. The WCCP Layer 2 PFC redirection feature requires no configuration on the MSFC. The show ip wccp web-cache detail command displays which redirection method is in use for each cache. Observe the following guidelines:

The WCCP Layer 2 PFC redirection feature sets the IP flow mask to full-flow mode.

You can configure Cisco Cache Engine software version 2.2 or later to use the WCCP Layer 2 PFC redirection feature.

Layer 2 redirection takes place on the switch and is not visible to the MSFC. The show ip wccp web-cache detail command on the MSFC displays statistics for only the first packet of a Layer 2 redirected flow, which provides an indication of how many flows, rather than packets, are using Layer 2 redirection. The display from the show mls entries command on the supervisor engine includes the other packets in Layer 2 redirected flows.

Configure WCCP as described in the Cisco IOS Configuration Fundamentals Configuration Guide, under "Configuring Web Cache Services Using WCCP," at this URL:

http://www.cisco.com/en/US/docs/ios/12_1/configfun/configuration/guide/fun_c.html

Jumbo Frame Feature on MSFC2

With an MSFC2, you can configure the MTU size on VLAN interfaces to support routing of jumbo frames. To configure the MTU value, perform this task:

 
Command
Purpose

Step 1 

Router(config)# interface vlan vlan_ID 

Accesses VLAN interface configuration mode.

Step 2 

Router(config-if)# mtu mtu_size 

Configures the MTU size. Valid values are from 64 to 17952 bytes.

Note Set the MTU size no larger than 9216, which is the size supported by the supervisor engine.

Step 3 

Router# show interface vlan 111

Verifies the configuration.

This example shows how to set the MTU size on a VLAN interface and verify the configuration:

Router(config)# interface vlan 111 
Router(config-if)# mtu 9216
Router(config-if)# end
Router# show interface vlan 111 | include MTU
MTU 9216 bytes, BW 1000000 Kbit, DLY 10 usec,
Router#

Configure support for jumbo frames on the supervisor engine as described in the "Configuring Ethernet, Fast Ethernet, and Gigabit Ethernet Switching" chapter of the Catalyst 6500 Series Software Configuration Guide.

ARP on STP Topology Change Notification

Router-Port Group Management Protocol

ARP on STP Topology Change Notification

The ARP on STP topology change notification feature ensures that excessive flooding does not occur when the MSFC receives a topology change notification (TCN) from the supervisor engine. The feature causes the MSFC to send ARP requests for all the ARP entries belonging to the VLAN interface where the TCN is received. When the ARP replies come back, the PFC learns the MAC entries, which were lost as a result of the topology change. Learning the entries immediately following a topology change prevents excessive flooding later. No configuration is required on the MSFC. This feature works with supervisor engine software release 5.4(2) or later.

Router-Port Group Management Protocol

These sections describe the Router-Port Group Management Protocol (RGMP):

Overview

Restrictions

Configuration Tasks

Overview

RGMP constrains multicast traffic that exits through ports to which disinterested multicast routers are connected. To effectively constrain traffic, RGMP must be supported on both the switches and the routers in the network.


Note CGMP and IGMP snooping constrain multicast traffic that exits through switch ports to which hosts are connected. They do not constrain traffic that exits through ports to which one or more multicast routers are connected.


Restrictions

The following restrictions apply to RGMP on the MSFC:

Sparse mode only—RGMP supports PIM sparse mode only. RGMP does not support PIM dense mode. RGMP explicitly supports the two AutoRP groups in dense mode by not restricting traffic to those groups but by flooding it to all router ports. For this reason, you should configure PIM sparse-dense mode. If you configure groups other than the AutoRP groups for dense mode, their traffic will not be correctly forwarded through router ports that have been enabled for RGMP.

You must enable IGMP snooping on the switch.

To effectively constrain multicast traffic with RGMP, connect RGMP-enabled routers to separate ports on RGMP-enabled switches.

RGMP only constrains traffic that exits through ports on which it detects an RGMP-enabled router. If a non-RGMP enabled router is detected on a port, that port receives all multicast traffic.

RGMP does not support directly connected sources in the network. A directly connected source will send traffic into the network without signaling this through RGMP or PIM. This traffic will not be received by an RGMP-enabled router unless the router already requested receipt of that group through RGMP. This restriction applies to hosts and to functions in routers that source multicast traffic, such as the ping and mtrace commands, and multicast applications that source multicast traffic, such as UDPTN.

RGMP supports directly connected receivers in the network. Traffic to these receivers will be restricted by IGMP snooping, or if the receiver is a router itself, by PIM and RGMP. CGMP is not supported in networks where RGMP is enabled on routers. Enabling RGMP and CGMP on a router interface is mutually exclusive. If RGMP is enabled on an interface, CGMP is silently disabled or vice versa.

The following properties of RGMP are the same as for IGMP snooping:

RGMP restricts traffic based on the multicast group, not on the sender's IP address.

If spanning tree topology changes occur in the network, the state is not flushed as it is with CGMP.

RGMP does not restrict traffic for the multicast groups 224.0.0.x (x = 0...255), allowing PIMv2 BSR to be used in an RGMP-controlled network.

RGMP in Cisco switches operates on MAC addresses, not on the IP multicast addresses. As more than one IP multicast addresses are mapped to one MAC address (refer to RFC 1112), no restriction of traffic occurs between different IP multicast groups that map to the same MAC address.

The capability of the switch to restrict traffic is limited by its CAM table capacity.

Configuration Tasks


Step 1 Establish an appropriate topology on the VLANs where you want to use RGMP.

Step 2 Enable RGMP on the switch:

Switch> (enable) set igmp enable 
Switch> (enable) set rgmp enable 

The first command enables IGMP snooping, and the second enables RGMP. Enabling these features on the switch is a global configuration. RGMP has no effect in those VLANs where there is not at least a single router also configured for RGMP.

Step 3 Enable RGMP on each interface that has a topology appropriate for RGMP:

Router(config)# vlan-interface 10
Router(config-if)# ip rgmp

Step 4 Monitor RGMP on the switch:

Switch> (enable) show  rgmp group [mac_addr] [vlan_id] 
Switch> (enable) show  rgmp group count [vlan_id] 
Switch> (enable) show  rgmp statistics [vlan_id] 
Switch> (enable) clear rgmp statistics
Switch> (enable) show  multicast router [igmp | rgmp] [mod/port] [vlan_id] 
Switch> (enable> show  multicast protocol status

Step 5 Monitor RGMP on the MSFC:

router(enable)# debug ip rgmp [name_or_group_address]


New Features in Earlier Releases

These sections describe the new features in earlier releases:

New Hardware Features in Earlier Releases

New Software Features in Earlier Releases

New Hardware Features in Earlier Releases

Release 12.0(3)XE1 provides initial support of the CAT6000-MSFC on the Catalyst 6500 series switches.

New Software Features in Earlier Releases

Release 12.0(7)XE1 supports high availability (HA) in supervisor engine software release 5.4(1) and later. No Cisco IOS commands or configuration are required on the MSFC for high availability (HA).

Release 12.0(7)XE1 supports the private VLAN (PVLAN) feature in supervisor engine software release 5.4(1) and later.

Enter the show pvlan command to display information about PVLANs.


Note The show pvlan command displays information about PVLANs only when the primary PVLAN is up.


Entering the set pvlan mapping or the clear pvlan mapping commands on the supervisor engine generates MSFC syslog messages as follows:

%PV-6-PV_MSG:Created a private vlan mapping, Primary 100, Secondary 101
%PV-6-PV_MSG:Created a private vlan mapping, Primary 200, Secondary 201
%PV-6-PV_MSG:Purged a private vlan mapping, Primary 100, Secondary 101

You can enter the interface vlan command to configure Layer 3 parameters only for primary PVLANs.

On the supervisor engine, you cannot create isolated or community VLANs using VLAN numbers for which the interface vlan commands have been entered on the MSFC.

ARP entries learned on Layer 3 PVLAN interfaces are sticky ARP entries. (We recommend that you display and verify PVLAN interface ARP entries.)

For security reasons, PVLAN interface sticky ARP entries do not age out. Connecting new equipment with the same IP address generates a message and the ARP entry is not created.

Because the PVLAN interface ARP entries do not age out, you must manually remove PVLAN interface ARP entries if a MAC address changes.

You can add or remove PVLAN ARP entries manually as follows:

Router(config)# no arp 11.1.3.30 
IP ARP:Deleting Sticky ARP entry 11.1.3.30

Router(config)# arp 11.1.3.30 0000.5403.2356 arpa 
IP ARP:Overwriting Sticky ARP entry 11.1.3.30, hw:00d0.bb09.266e by 
hw:0000.5403.2356

Some commands clear and recreate PVLAN mapping as follows:

Router(config)# xns routing 
Router(config)#
%PV-6-PV_MSG:Purged a private vlan mapping, Primary 100, Secondary 101
%PV-6-PV_MSG:Purged a private vlan mapping, Primary 100, Secondary 102
%PV-6-PV_MSG:Purged a private vlan mapping, Primary 100, Secondary 103
%PV-6-PV_MSG:Created a private vlan mapping, Primary 100, Secondary 101
%PV-6-PV_MSG:Created a private vlan mapping, Primary 100, Secondary 102
%PV-6-PV_MSG:Created a private vlan mapping, Primary 100, Secondary 103

The features listed below were introduced but not fully tested at wire rate in supervisor engine software release 5.3(1a)CSX and Releases 12.0(3)XE1 and 12.0(3)XE2. They have been fully tested in software release 5.3(3)CSX and Release 12.0(7)XE and are fully operational.

IPX multilayer switching (MLS) at wire rate (software release 5.3(1a)CSX or later and Release 12.0(7)XE or later support IPX routing at wire rate).

Cisco IOS IPX ACLs at wire rate (software release 5.3(1a)CSX or later and Release 12.0(7)XE or later support standard and extended Cisco IOS IPX ACLs at wire rate).

QoS IPX ACLs.

Release 12.0(3)XE1 provides initial support of the MSFC1 on the Catalyst 6500 series switches.

Limitations and Restrictions

These sections describe limitations and restrictions:

MSFC Limitations and Restrictions

FlexWAN Module Limitations and Restrictions

OSM Limitations and Restrictions


NoteFor multicast flows, the PFC does not provide Layer 3 switching on output interfaces with MTU sizes smaller than the flow's input interface MTU size. The workaround is to configure the same MTU size on both the input and output interfaces. (CSCds42685)

Cisco IOS images for the MSFC and MSFC2 do not support time-based ACLs.


MSFC Limitations and Restrictions

IPsec in software on the MSFC is supported only for administrative connections to Catalyst 6500 series switches and Cisco 7600 series routers.

In Release 12.1(19)E and later releases, you cannot disable IP routing. (CSCdu05871)

After high availability (HA) switchover, the redundant MSFC might remain in the "other" state. (CSCdw79129)

Before you can enable single-router mode (SRM) on the MSFC, high availability must be enabled on the supervisor engine. Failure to do so might result in unexpected system behavior. With Catalyst software releases earlier than 7.1(1), no syslog message is generated when SRM is enabled with high availability disabled on the supervisor engine. (CSCdu78927)

With SRM configured, IP traffic is software switched by the MSFC for several minutes after a switchover to the redundant supervisor engine and MSFC. (CSCdv25906)

When the outgoing interface list for group G traffic transitions to null on a last-hop multicast router, the router sends a (*,G) prune message to the PIM neighbor toward the rendezvous point (RP) to stop the flow of group G traffic (if any) down the shared tree. The last-hop multicast router does not send an (S,G) prune message to stop the flow of traffic down the shortest path tree (SPT). The transition of the outgoing interface list to null does not trigger an (S,G) prune message. (S,G) prune messages are triggered by the arrival of (S,G) traffic.

If the last-hop multicast router is a Catalyst 6500 series switch, traffic is forwarded by the PFC2. In most cases, RPF-MFD is installed for the (S,G) entries. The MSFC2 does not see the multicast traffic flowing down the SPT and does not send any traffic-triggered (S,G) prunes to stop the flow of traffic down the SPT. This situation does not have any adverse effect on the MSFC2 because the PFC2 processes and drops the unwanted (S,G) traffic. (CSCdu40065)

Integrated routing and bridging (IRB) and concurrent routing and bridging (CRB) have deliberately been disabled on the Catalyst 6500 series switches. Layer 2 VLANs and VLAN interfaces should be used for normal bridging and interVLAN routing. Bridge groups are supported only to bridge nonrouted protocols. (CSCdz21959)

With Release 12.1(6)E or later, FlexWAN module interfaces support dNBAR. Do not configure NBAR on other interfaces.

Catalyst 6500 series switches do not support remote source-route bridging (RSRB).

With MISTP configured on the supervisor engine, use only the vlan-bridge or dec Spanning Tree Protocols for bridge groups on the MSFC. We recommend the vlan-bridge Spanning Tree Protocol. With MISTP configured on the supervisor engine, the MSFC does not support the IEEE Spanning Tree Protocol. This restriction does not apply to PVST+ or MISTP-PVST+. (CSCdr99236, CSCds09253)

With a PFC2, if you enter the mac mac_address interface command, the configured MAC address is used for all VLAN interfaces.

The PFC2 supports a maximum of 1 Gateway Load Balancing Protocol (GLBP) group.

The PFC2 supports a maximum of 16 unique Hot Standby Routing Protocol (HSRP) group numbers.

You can use the same HSRP group numbers in different VLANs (for example, use 1 as the first group number in each VLAN, use 2 for the second, etc.).

If you configure more than 16 HSRP groups, this restriction prevents use of the VLAN number as the HSRP group number.

Use the same Spanning Tree Protocol on all devices that are bridging between VLANs.

With Supervisor Engine 2 (running Catalyst software), PFC2, and MSFC2, IP unreachable messages and IP redirects are automatically disabled if you configure secondary addresses on a VLAN to avoid out-of order packets when packets are routed between two subnets on the same VLAN. (CSCdr84706)

MSFC2 does not support the MultiNode Load Balancing (MNLB) forwarding agent of the MNLB feature set for LocalDirector. (CSCdr65433)

The ip multicast rate-limit command is not supported on Catalyst 6500 series switch LAN ports. Refer to the "Configuring QoS" chapter of the Catalyst 6500 Series Software Configuration Guide for information about policing. (CSCds22281)

If you are using the Catalyst 6500 series switch to handle thousands of IPX flows that might all arrive in simultaneous bursts, we recommend that you enter the following command to avoid excessive CPU load:

Router(config)# ipx route-cache inactivity-timeout 1 100  

This command sets the IPX cache inactivity timeout to 1 minute and the maximum invalidations per minute to 100.

Before you can use a system image stored on the supervisor engine Flash PC card, you must set the BOOTLDR environment variable. In privileged mode, enter the boot bootldr bootflash: boot_loader_image command.

To boot a system image stored on the supervisor engine Flash PC card, at least one VLAN interface must be configured and be active.

Data-link Switching plus (DLSw+) was mistakenly identified as not being supported in MSFC Cisco IOS Release 12.0(3)XE1 and subsequent releases. DLSw+ is supported in Release 12.0(3)XE1 and subsequent releases.

Cisco IOS Release 12.0(3)XE1 and later supports the Web Cache Control Protocol (WCCP) feature, versions 1 and 2.

At power up or manual reset, you must configure the MSFC to boot from its bootflash (or the supervisor engine's Flash PC card; however, bootflash is preferred). When you reset the supervisor engine through either a power up or a manual reset, the MSFC cannot boot from a TFTP server on the network. However, when the supervisor engine is up and the port over which the network is being accessed is in forwarding state, you can boot the MSFC from a TFTP server on the network.

In a redundant supervisor engine setup, if a specific VLAN interface on one MSFC shuts down, you should manually shut down the corresponding VLAN interface on the other MSFC.

By default, the MSFC sends Internet Control Message Protocol (ICMP) unreachable messages when a packet is denied by an access group; these access-group-denied packets are not dropped in hardware but are bridged to the MSFC so it can generate the ICMP-unreachable message. To drop access-group-denied packets in hardware, you must disable ICMP unreachable messages using the no ip unreachables interface configuration command. The ip unreachables command is enabled by default.

You can specify the MSFC as the multilayer switching route processor (MLS-RP) for Catalyst 5000 family switches using MLS. Refer to the Layer 3 Switching Configuration Guide—Catalyst 5000 Family, 4000 Family, 2926G Series, 2926 Series, 2948G for MLS configuration procedures.

If one MSFC fails in a system with redundant MSFCs, second hop routers could continue to send traffic to the failed MSFC for a period of time until the second hop router realizes that the MSFC is down.

HSRP addresses only first hop redundancy; it ensures that the default gateway configured on the clients (workstations) remains up even if one router from the HSRP group goes down.

HSRP ensures that traffic going from the client through the default gateway to the ultimate destination is supported with the loss of one MSFC.

The HSRP MAC and IP addresses are never known to the other routers, which means that the reverse traffic from the destination to the originating client may or may not go through the same router. This situation is especially true if the source and destination are more than one hop away. The second hop router (from the client) sees that the client is reachable through both the MSFCs and through load balancing, and the router could spread the reverse traffic between the two MSFCs.

When one MSFC fails, the HSRP quickly detects the failure (10 seconds based on default HSRP settings), which means that traffic from the client to its destination goes through. However, the second hop router has to rely on the routing protocol's (RIP/OSPF) convergence time (from 30 to 90 seconds) to realize that one MSFC is down and will try to send the reverse traffic to the failed MSFC.

The reverse traffic can flow through either MSFC if the source and destination are more than one hop away.

NetFlow Data Export (NDE) version 7 is not supported for multilayer switching (MLS) statistics exported from the MSFC. Statistics exported from the supervisor engine use NDE version 7.

When using the Network Address Translation (NAT) router feature on the MSFC, packets traversing the NAT outside interface might, under certain configurations, be software routed instead of being shortcut, regardless of whether they should or should not be translated. Ideally, for packets traversing the NAT outside interface, you would want only those packets requiring NAT to be software routed. Cisco IOS software will only translate traffic in software that is traversing from NAT inside interfaces to NAT outside interfaces and vice versa.

By making the access control list (ACL) used for NAT more specific, you can limit the software-handled packets to only those requiring NAT translation.

For example, if you use a general ACL (such as permit ip any any) to specify the traffic that requires NAT, then all traffic inbound or outbound on the NAT outside interface will be software routed (including traffic not originating or destined to NAT inside interfaces). If it is possible to use a more specific ACL (such as permit ip 10.1.1.0 0.0.0.255 any), then only the NAT outside traffic matching that ACL will be software routed. This traffic will still be software routed regardless of whether it is originating or destined to NAT inside interfaces. By making the ACL more specific, you can limit the amount of traffic that is software routed due to the NAT ACL.

ACL configuration guidelines: When configuring ACLs on an interface with the configuration command tcam priority {high | low | normal}, entering high ternary content addressable memory (TCAM) priority gives ACLs on that interface priority for getting into the TCAM over ACLs of interfaces with lower (low or normal) priority.

If the ACLs on an interface with high priority do not fit in the TCAM, the ACLs for interfaces of lower priority will not be inserted into the TCAM until it is possible to fit the high-priority ACLs into the TCAM.

With Supervisor Engine 1, output ACLs that deny traffic cannot be applied in hardware if the traffic is not being Layer 3 switched by the PFC. (CSCdv55854)

You can configure VLAN access control lists (VACLs) on the switch to apply to all packets that are routed into or out of a VLAN or that are bridged within a VLAN. VACLs are strictly for security packet filtering and redirecting traffic to specific physical switch ports. Unlike Cisco IOS ACLs, VACLs are not defined by direction (input or output). Refer to the "Configuring Access Control Lists" chapter of the Catalyst 6500 Series Software Configuration Guide.

MAC address-based Cisco IOS ACLs are not supported for packets shortcut in hardware. MAC address-based Cisco IOS ACLs will be applied on software-switched packets. MAC address-based access control can be supported in hardware for non-IP/IPX packets using VACLs. We recommend that you use VACLs to do MAC-addressed-based ACLs.

Broadcast-to-multicast translation used with the multicast helper command does not work if a flow is hardware switched.

If TFTP downloads (net boots) are timing out, use the following Cisco IOS global configuration command for TFTP booting:

ip tftp boot-interface tftp_interface 

where tftp_interface is the interface the TFTP boot server is on.

If you enable multicast routing globally, then you should also enable multicast routing (using the ip pim command) on all Layer 3 interfaces on which you anticipate receiving IP multicast traffic. This command causes the packets to be sent to the process switching level for creating the route entry. However, if you disable multicast routing on the RPF interface, the entry cannot be created and the packet is dropped. Exceeding the source-traffic rate that can be handled by the process level can have an undesirable impact on the system. For instance, HSRP timers can expire on a standby router and cause HSRP flapping.

Delivery acknowledgment timeouts might occur:

SCP-4-DACK_TIMEOUT_MSG:SCP delivery ack timeout for opcode=118 

When a delivery acknowledgment timeout occurs for opcode 118 (that is, multicast MLS SCP messages), then the impact depends on whether multicast multilayer switching (MMLS) is in IDLE or ACTIVE state (can be determined by entering the show mls ip multicast statistics command). If MMLS is active, the message is only a warning and can be ignored. If MMLS is idle, this message displays:

Multicast MLS is disabled due to internal messaging error 

The feature is disabled on the MSFC. You must disable and reenable the IGMP feature on the supervisor engine before reenabling MMLS on the MSFC.

After enabling PIM on an interface, you need to enter the ip mroute-cache command on the interface to enable multicast fast switching. If you have "no ip mroute-cache" configured, multicast packets that are not hardware switched will go to a process level. This process increases the load on the router. Software fast switching is useful for flows that can only be partially hardware switched.

A Supervisor Engine 2 with PFC2 and MSFC2 automatically reserves a MAC address for the nondesignated MSFC2, whether or not a nondesignated MSFC2 is present. The MAC address automatically reserved for the nondesignated MSFC2 is identical to the MAC address of the designated MSFC2, except for the least significant bit, which is toggled. For example, if the least significant bit in the MAC address of the designated MSFC2 is zero, the least significant bit in the MAC address reserved for the nondesignated MSFC2 will be one.

After a MAC address has been automatically reserved for the nondesignated MSFC2, the PFC2 assumes that any traffic for the reserved address is intended for the nondesignated MSFC2 even if there is no nondesignated MSFC2 installed. If you assign the reserved MAC address to another router or host, the PFC2 will not forward traffic to that external address because the PFC2 incorrectly assumes that traffic for the reserved address is for the nondesignated MSFC2.

Enter the show mls cef mac supervisor engine command to display the MAC address of the designated MSFC2. (CSCdr55163)

The scheduler allocate command is enabled by default to provide adequate process level cycles under heavy switching loads. (CSCdp90088)

With Supervisor Engine 1 and PFC, when you upgrade from Release 12.1(2)E to 12.1(3a)E2, it is safe to ignore "ip cef incomplete command" error messages. (CSCds43045)

Topology changes that occur in MISTP spanning tree instances on the supervisor engine are not detected by the vlan-bridge or dec Spanning Tree Protocols. MISTP spanning tree instances do not detect topology changes in vlan-bridge or dec spanning tree instances. Spanning tree instances that fail to detect topology changes in adjoining spanning tree instances do not age out address tables, which can then result in some loss of connectivity while stale address table ages out (typically, within the standard aging time of 300 seconds). MISTP-PVST+ mode detects topology changes in IEEE STP bridge groups. (CSCds19906)

The c6msfc2-boot-mz.121-3a.E7 boot image is not compatible with Catalyst software release 7.1(2). (CSCdw78898)

In a redundant configuration, IP access lists can prevent the MSFC from pinging its own interface IP address or the interface HSRP IP address. (CSCdp77698)

Fast-switched IP multicast traffic that matches a permit access list entry with the log keyword is dropped. Fast switching of IP multicast packets is enabled by default. (CSCds28581)

For the RTR agent to send out traps, enter the rtr reaction-configuration 2 timeout-enable action-type traponly command. (CSCdz58158)

With some third-party cache appliances connected and WCCP configured, when one cache appliance fails or is disconnected, WCCP redirection to the remaining cache appliance stops. (CSCea00469)

FlexWAN Module Limitations and Restrictions

The FlexWAN module does not support IPX CEF for PFC2 or IPX multilayer switching (MLS) with Release 12.1(6)E and earlier.

To use the interfaces on the FlexWAN module, you must enable IP routing on the MSFC. (CSCdp34896)

Named access lists are not supported on the FlexWAN.

To avoid MSFC2 reloads, enter the no vines route-cache interface command so that VINES traffic is process switched. (CSCdr61424)

OSM Limitations and Restrictions

The Packet-over-SONET (POS) network interface configuration might be erased when you upgrade to Release 12.1(13)E3 from a Release 12.1(8b)E image or a Release 12.1(11b)E image.

Workaround: Copy the POS configuration from the startup configuration to the running configuration. (CSCdz66653, CSCdx89907)

The OSMs are supported only in systems with a Supervisor Engine 2.

The Layer 3 Gigabit Ethernet WAN interfaces on the Gigabit Ethernet WAN (GBIC) OSMs do not support Gigabit EtherChannel or bridging.

To avoid subjecting routing protocol packets to policy-based routing, configure filtering in route maps so that it does not match routing protocol packets. (CSCds44369)

Two vulnerabilities exist in the virtual private dial-up network (VPDN) solution when Point-to-Point Tunneling Protocol (PPTP) is used in certain Cisco IOS releases prior to 12.3. PPTP is only one of the supported tunneling protocols used to tunnel PPP frames within the VPDN solution.

The first vulnerability is a memory leak that occurs as a result of PPTP session termination. The second vulnerability may consume all interface descriptor blocks on the affected device because those devices will not reuse virtual access interfaces. If these vulnerabilities are repeatedly exploited, the memory and/or interface resources of the attacked device may be depleted.

Cisco has made free software available to address these vulnerabilities for affected customers.

There are no workarounds available to mitigate the effects of these vulnerabilities.

The Cisco Next Hop Resolution Protocol (NHRP) feature in Cisco IOS contains a vulnerability that can result in a restart of the device or possible remote code execution.

NHRP is a primary component of the Dynamic Multipoint Virtual Private Network (DMVPN) feature.

NHRP can operate in three ways: at the link layer (Layer 2), over Generic Routing Encapsulation (GRE) and multipoint GRE (mGRE) tunnels and directly on IP (IP protocol number 54). This vulnerability affects all three methods of operation.

NHRP is not enabled by default for Cisco IOS.

This vulnerability is addressed by Cisco bug IDs CSCin95836 for non-12.2 mainline releases and CSCsi23231 for 12.2 mainline releases.

Closing a Telnet session may cause a reload. This problem is resolved in Release 12.1(27b)E2. (CSCds33629)

In rare situations, intensive SNMP polling might use all available I/O memory. This problem is resolved in Release 12.1(27b)E2. (CSCeg11566)

For a system configured as an IP HTTP server, tracebacks and a reload might occur during HTTP transactions with URL tokens greater than 128 characters long. A token is a string delimited by slashes in a URL. This problem is resolved in Release 12.1(27b)E2. (CSCeg62070)

In certain LAN topologies, the PIM assert mechanism can cause an upstream router to erroneously remove downstream interfaces from output interface lists. When this situation occurs, it causes multicast traffic to be dropped. This problem occurs when two or more upstream routers with routes to the same rendezvous point or traffic source are connected to the same LAN segment as two different downstream routers. The problem occurs when the two downstream routers select different upstream routers as their next hop. This problem is resolved in Release 12.1(27b)E2. (CSCeh17756)

A Cisco IOS device may crash while processing malformed Secure Sockets Layer (SSL) packets. In order to trigger these vulnerabilities, a malicious client must send malformed packets during the SSL protocol exchange with the vulnerable device.

Successful repeated exploitation of any of these vulnerabilities may lead to a sustained Denial-of-Service (DoS); however, vulnerabilities are not known to compromise either the confidentiality or integrity of the data or the device. These vulnerabilities are not believed to allow an attacker will not be able to decrypt any previously encrypted information.

Cisco IOS is affected by the following vulnerabilities:
