Release Notes for Cisco IOS Release 12.2ZY on the Supervisor Engine 32 PISA

---

---

---

Supervisor Engine 32 PISA (CAT6000-SUP32/PISA)

These sections describe the Supervisor Engine 32 PISA:

• Supervisor Engine 32 PISA Restrictions
• Supervisor Engine 32 PISA Features

Supervisor Engine 32 PISA Restrictions

• Supervisor Engine 32 PISA requires a high-capacity fan tray (see the “Fan Trays” section).
• In some chassis, Supervisor Engine 32 PISA requires a high-capacity power supply (see the “Power Supplies” section).

Supervisor Engine 32 PISA Features

 

Policy Feature Cards

• Policy Feature Card Guidelines and Restrictions
• Policy Feature Card 3B

Policy Feature Card Guidelines and Restrictions

• The PFC3B supports a theoretical maximum of 64 K MAC addresses (32 K MAC addresses recommended maximum).
• The PFC3B partitions the hardware FIB table to route IPv4 unicast, IPv4 multicast, MPLS, and IPv6 unicast and multicast traffic in hardware. Traffic for routes that do not have entries in the hardware FIB table are routed by the PISA in software.

The defaults are:

– IPv4 unicast and MPLS—192,000 routes

– IPv4 multicast and IPv6 unicast and multicast—32,000 routes

---

Note The size of the global internet routing table plus any local routes might exceed the default partition sizes.

These are the theoretical maximum numbers of routes for the supported protocols (the maximums are not supported simultaneously):

– IPv4 and MPLS—Up to 239,000 routes

– IPv4 multicast and IPv6 unicast and multicast—Up to 119,000 routes

Enter the mls cef maximum-routes command to repartition the hardware FIB table. IPv4 unicast and MPLS require one hardware FIB table entry per route. IPv4 multicast and IPv6 unicast and multicast require two hardware FIB table entries per route. Changing the partition for one protocol makes corresponding changes in the partitions of the other protocols. You must enter the reload command to put configuration changes made with the mls cef maximum-routes command into effect.

• Enter the show platform hardware pfc mode command to display the PFC mode.
• The Supervisor Engine 32 PISA operates in PFC3B mode.

• Cisco Nonstop Forwarding (NSF) with stateful switchover (SSO) supervisor engine redundancy—See this publication:

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2ZY/configuration/guide/nsfsso.html

---

Note ● NSF with SSO supports multicast traffic.

• NSF with SSO redundancy mode supports IPv4. NSF with SSO redundancy mode does not support IPv6, IPX, or MPLS.
• These protocols can coexist with NSF with SSO redundancy mode, but there is no stateful support for them:

– MPLS and LDP

– GLBP

– HSRP

– VRRP

• Following an NSF with SSO switchover, traffic loss occurs on the links where the protocols are configured until the protocols converge.
• With Firewall Services Module Software Release 2.3(1), WS-SVC-FWM-1-K9 maintains state when an NSF with SSO redundancy mode switchover occurs.

 

• Clear hardware interface counters—See this publication:

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2ZY/command/reference/cmdref.html

• CNS Interactive CLI—Network management applications can use the Cisco Networking Services (CNS) agents to manage network routers. The CNS agent provides the capability to send commands to a router from a programmable source. The CNS Interactive CLI feature introduces a new XML interface that allows you to send interactive commands to a router, such as commands that generate prompts for user input. A benefit of this feature is that interactive commands can be terminated before they have been fully processed. For example, for commands that generate a significant amount of output, the XML interface can be customized to limit the size of the output or the length of time allowed for the output to accumulate. The capability to use a programmable interface to terminate a command before its normal termination (similar to manually terminating a command) can greatly increase the efficiency of diagnostic applications that might use this functionality. The new XML interface also allows for multiple commands to be processed in a single session. The response for each command is packaged together and sent in a single response event.
• Configurable Per VLAN MAC Learning (PVL)—See the mac-address-table learning command in this publication:

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2ZY/command/reference/cmdref.html

• Control Plane DSCP Support for RSVP—See this publication:

http://www.cisco.com/en/US/docs/ios-xml/ios/qos_rsvp/configuration/15-mt/rsvp-dscp-spt-for-rsvp.html

• IP-in-IP tunneling and generic routing encapsulation (GRE) tunneling supported in hardware—The PFC3B supports the following tunnel commands:

– tunnel destination

– tunnel mode gre

– tunnel mode ipip

– tunnel source

– tunnel ttl

– tunnel tos

Other supported types of tunneling run in software on the PISA. The PFC3B does not provide hardware acceleration for tunnels configured with the tunnel key command.

The tunnel ttl command (default 255) sets the TTL of encapsulated packets.

The tunnel tos command, if present, sets the ToS byte of a packet when it is encapsulated. If the tunnel tos command is not present and QoS is not enabled, the ToS byte of a packet sets the ToS byte of the packet when it is encapsulated. If the tunnel tos command is not present and QoS is enabled, the ToS byte of a packet as modified by PFC QoS sets the ToS byte of the packet when it is encapsulated.

To configure GRE Tunneling and IP in IP Tunneling, refer to these publications:

http://www.cisco.com/en/US/docs/ios/12_2/interface/configuration/guide/icflogin.html

http://www.cisco.com/en/US/docs/ios/12_2/interface/command/reference/irfshoip.html

To configure the tunnel tos and tunnel ttl commands, refer to this publication:

http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/12s_tos.html

Note the following information about tunnels:

– Each hardware-assisted tunnel must have a unique source. Hardware-assisted tunnels cannot share a source even if the destinations are different. Use secondary addresses on loopback interfaces or create multiple loopback interfaces. (CSCdy72539)

– Each tunnel interface uses one internal VLAN.

– Each tunnel interface uses one additional router MAC address entry per router MAC address.

– The PFC3B supports PFC QoS features on tunnel interfaces.

– The PFC3B supports GRE tunnel encapsulation and de-encapsulation of multicast traffic.

– The PISA supports tunnels configured with egress features on the tunnel interface. Examples of egress features are output Cisco IOS ACLs, NAT and PAT (for inside to outside translation), TCP intercept, context-based access control (CBAC), and encryption.

• MQC: distribution of remaining bandwidth (supported only on WAN ports)—You configure QoS features on an interface using the modular QoS CLI (MQC). Using MQC, you create service policies for traffic classes and attach the policies to an interface. You can use MQC to specify how the remaining bandwidth is distributed among the interface or subinterface output queues. The remaining bandwidth is the available bandwidth left on an interface or subinterface after all guaranteed traffic is accounted for. The amount of remaining bandwidth available for use is determined by the excess information rate (EIR) configured for the queue.

The bandwidth remaining percent command allows you to configure the remaining bandwidth for output queues. The aggregate of all user-configured EIR bandwidth percentages cannot exceed 100 percent. If the aggregate of all remaining bandwidth is less than 100 percent, the remainder is evenly split among user queues (including the default queue) that do not have a remaining bandwidth percentage configured. The minimum EIR value of each output queue is 1.

This example shows how to use the bandwidth remaining percent command to distribute percentages of remaining bandwidth to various traffic classes in a policy map:

– The NetFlow Multicast Support document contains a prerequisite that does not apply when configuring NetFlow multicast support with Release 12.2(18)ZY and later 12.2ZY releases:

You do not need to configure multicast fast switching or multicast distributed fast switching (MDFS); multicast CEF switching is supported with Release 12.2(18)ZY and later 12.2ZY releases.

• Network Address Translation (NAT) and Port Address Translation (PAT) for IPv4 unicast and multicast traffic (hardware-assisted)—Note the following information about hardware-assisted NAT:

– PFC3B mode supports NAT and PAT for UDP traffic.

– The PFC3B does not support NAT or PAT for multicast traffic.

– The PFC3B does not support NAT or PAT configured with a route map that specifies length.

– The PFC3B does not support NAT or PAT configured with a route map that specifies static translations.

– When you configure NAT or PAT and NDE on an interface, the PFC3B sends all traffic in fragmented packets to the PISA to be processed in software. (CSCdz51590)

To configure NAT or PAT, refer to the Cisco IOS IP Configuration Guide, Release 12.2, “IP Addressing and Services,” “Configuring IP Addressing,” “Configuring Network Address Translation,” at this URL:

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

http://www.cisco.com/en/US/tech/tk648/tk361/technologies_q_and_a_item09186a00800e523b.shtml

To prevent a significant volume of NAT or PAT traffic from being sent to the PISA, due to either a DoS attack or a misconfiguration, enter the mls rate-limit unicast acl { ingress | egress } command described in this publication:

• Policy-based routing (PBR; hardware-assisted) for route-map sequences that use the match ip address, set ip next-hop, and set ip default next-hop PBR keywords.

To configure PBR, refer to the Cisco IOS Quality of Service Solutions Configuration Guide, Release 12.2, “Classification,” “Configuring Policy-Based Routing,” at this URL:

http://www.cisco.com/en/US/docs/ios/12_2/qos/configuration/guide/qcfpbr_ps1835_TSD_Products_Configuration_Guide_Chapter.html

When configuring PBR, follow these guidelines and restrictions:

– The PFC provides hardware support for PBR configured on a tunnel interface.

– The PFC does not provides hardware support for PBR configured with the set ip next-hop keywords if the next hop is a tunnel interface.

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

– Any options in Cisco IOS ACLs that provide filtering in a PBR route map that would cause flows to be sent to the PISA to be switched in software are ignored. For example, logging is not supported in ACEs in Cisco IOS ACLs that provide filtering in PBR route maps.

– PBR traffic through switching module ports where PBR is configured is routed in software if the switching module resets. (CSCee92191)
