Cisco IOS Software Packaging for the Cisco Catalyst 4500 Series

A new Cisco IOS Software package for Cisco Catalyst 4500 Series Switches was introduced in Cisco IOS Software Release 12.2(25)SG. It is a new foundation for features and functionality and provides consistency across all Cisco Catalyst switches. The new Cisco IOS Software release train is designated as 12.2SG.

Prior Cisco Catalyst 4500 Series IOS Software images for the Cisco Catalyst 4500 Series Switches, formerly known as Basic Layer 3 and Enhanced Layer 3, now map to IP Base and Enterprise Services, respectively. All currently shipping Cisco Catalyst 4500 software features based on Cisco IOS Software are supported in the IP Base image of Release 12.2(53)SG, with a few exceptions.

The IP Base image does not support enhanced routing features such as NSF/SSO, BGP, EIGRP, EIGRPv6, OSPF, OSPFv3, IS-IS, Internetwork Packet Exchange (IPX), AppleTalk, VRF-lite, and Policy-Based Routing (PBR). The IP Base image supports EIGRP-Stub for limited routing on Supervisor Engines II-Plus, II-Plus-TS, II-Plus-10GE, IV, V, V-10GE, and 6-E.

The Enterprise Services image supports all Cisco Catalyst 4500 Series software features based on Cisco IOS Software, including enhanced routing. Customers planning to enable BGP for Supervisor Engine IV, V, or V-10GE will no longer need to purchase a separate BGP license (FR-IRC4) because BGP is included in the Enterprise Services package.

Cisco IOS Release 12.2(46)SG1 introduced a new LAN Base software and an IP upgrade image. These complement the existing IP Base and Enterprise Services images. The LAN base image is supported on the Supervisor Engine II-Plus-10GE and Supervisor Engine 6L-E starting with
Cisco IOS Release 12.2(52)XO. LAN Base image is primarily focused on customer access and Layer 2 requirements and therefore many of the IP Base features are not required. The IP upgrade image is available if at a later date you require some of those features.

Figure 1 illustrates feature support within the 3 packages: LAN Base, IP Base, and Enterprise Services. This is not a detailed list.

Please visit Feature Navigator for full package details: http://tools.cisco.com/ITDIT/CFN/.

Figure 1 Feature Support by Package

Table 1 contrasts feature support on the LAN Base vs IP Base images.

---

Note You can purchase a special license to enable the 10 Gigabit uplinks in the LAN Base image without moving to IP Base.

---

---

Note By default all the Features are supported on Enterprise Services image.

New Hardware Features in Release 12.2(53)SG

Release 12.2(53)SG does not provide any new hardware for the Catalyst 4500 series switch. However, it does integrate Supervisor Engine 6L-E, introduced in 12.2(52)XO.

New Software Features in Release 12.2(53)SG

Release 12.2(53)SG provides the following Cisco IOS software features for the Catalyst 4500 series switch:

•IP Multicast Load Splitting (Equal Cost Multipath (ECMP) using S, G and Next-hop)

•OSPF for Routed Access (Supervisor Engine 6-E and Supervisor Engine 6L-E)

OSPF for Routed Access is designed specifically to enable customers to extend Layer 3 routing capabilities to the access or Wiring Closet.

---

Note OSPF for Routed Access supports only one OSPFv2 and one OSPFv3 instance with a maximum number of 200 dynamically learned routes.

---

With the typical topology (hub and spoke) in a campus environment, where the wiring closets (spokes) are connected to the distribution switch (hub) forwarding all nonlocal traffic to the distribution layer, the wiring closet switch need not hold a complete routing table. A best practice design, where the distribution switch sends a default route to the wiring closet switch to reach inter-area and external routes (OSPF stub or totally stub area configuration) should be used when OSPF for Routed Access is used in the wiring closet.

Refer to the following link for more details:

http://www.cisco.com/en/US/docs/solutions/Enterprise/Campus/routed-ex.html

With Cisco IOS Release 12.2(53)SG, the IP Base image supports OSPF for routed access. The Enterprise Services image is required if you need multiple OSPFv2 and OSPFv3 instances without route restrictions. Additionally, Enterprise Services is required to enable the VRF-lite feature.

Upgrading the System Software

In most cases, upgrading the switch to a newer release of Cisco IOS software does not require a ROMMON upgrade. However, if you are running an early release of Cisco IOS software and plan to upgrade, refer to the following tables for the minimum Cisco IOS image and the recommended ROMMON release, respectively.

---

Caution Most supervisor engines have the required ROMMON release. However, due to caveat CSCed25996, we recommend that you upgrade your ROMMON to the recommended release.

The following sections describe how to upgrade your switch software:

•Guidelines for Upgrading the ROMMON

•Upgrading the Supervisor Engine ROMMON from the Console

•Upgrading the Supervisor Engine ROMMON Remotely Using Telnet

•Upgrading the Cisco IOS Software

Guidelines for Upgrading the ROMMON

---

Caution If your supervisor engine is shipped with a newer version of ROMMON then do not downgrade! The new ROMMON will have board settings based on a hardware revision of components, and old settings will not work.

---

Upgrading the Supervisor Engine ROMMON from the Console

---

Caution To avoid actions that might make your system unable to boot, read this entire section before starting the upgrade.

---

---

Note The examples in this section use the programmable read-only memory (PROM) upgrade version 12.1(20r)EW1 and Cisco IOS Release 12.1(20)EW1. For other releases, replace the ROMMON release and Cisco IOS software release with the appropriate releases and filenames.

---

Follow this procedure to upgrade your supervisor engine ROMMON:

---

Step 1 Directly connect a serial cable to the console port of the supervisor engine.

---

Note This section assumes that the console baud rate is set to 9600 (default). If you want to use a different baud rate, change the configuration register value for your switch.

---

Step 2 Download the cat4000-ios-promupgrade-121_20r_EW1 program from Cisco.com, and place it on a TFTP server in a directory that is accessible from the switch that is upgraded.

The cat4000-ios-promupgrade-121_20r_EW1 programs are available on Cisco.com at the same location from which you download Catalyst 4000 system images.

Step 3 Use the dir bootflash: command to ensure that there is sufficient space in Flash memory to store the PROM upgrade image. If there is insufficient space, delete one or more images, and then enter the
squeeze bootflash: command to reclaim the space.

If you are using a CompactFlash card, replace bootflash: with slot0:.

Step 4 Download the cat4000-ios-promupgrade-121_20r_EW1 program into Flash memory using the copy tftp command.

The following example shows how to download the PROM upgrade image cat4000-ios-promupgrade-121_20r_EW1 from the remote host 172.20.58.78 to bootflash:

Switch# copy tftp: bootflash: 
Address or name of remote host [172.20.58.78]?  
Source filename [cat4000-ios-promupgrade-121_20r_EW1]?  
Destination filename [cat4000-ios-promupgrade-121_20r_EW1]?  
Accessing tftp://172.20.58.78/cat4000-ios-promupgrade-121_20r_EW1...

The ROMMON has now been upgraded.

See the "Upgrading the Cisco IOS Software" section for instructions on how to upgrade the Cisco IOS software on your switch.

Upgrading the Supervisor Engine ROMMON Remotely Using Telnet

---

Caution To avoid actions that might make your system unable to boot, read this entire section before starting the upgrade.

---

Follow this procedure to upgrade your supervisor engine ROMMON to Release 12.1(20r)EW1. This procedure can be used when console access is not available and when the ROMMON upgrade must be performed remotely.

---

Note In the following section, use the PROM upgrade version cat4000-ios-promupgrade-121_20r_EW1.

---

---

Step 1 Establish a Telnet session to the supervisor engine.

---

Note In the following discussion, we assume that at least one IP address has been assigned to either an SVI or a routed port.

---

Step 2 Download the cat4000-ios-promupgrade-121_20r_EW1 program from Cisco.com, and place it on a TFTP server in a directory that is accessible from the switch to be upgraded.

The cat4000-ios-promupgrade-121_20r_EW1 programs are available on Cisco.com at the same location from which you download Catalyst 4500 system images.

Step 3 Use the dir bootflash: command to ensure that there is sufficient space in Flash memory to store the PROM upgrade image. If there is insufficient space, delete one or more images, and then enter the
squeeze bootflash: command to reclaim the space.

If you are using a CompactFlash card, replace bootflash: with slot0:.

Step 4 Download the cat4000-ios-promupgrade-121_20r_EW1 program into Flash memory using the
copy tftp command.

The following example shows how to download the PROM upgrade image cat4000-ios-promupgrade-121_20r_EW1 from the remote host 172.20.58.78 to bootflash:

Switch# copy tftp: bootflash: 
Address or name of remote host [172.20.58.78]?  
Source filename [cat4000-ios-promupgrade-121_20r_EW1]?  
Destination filename [cat4000-ios-promupgrade-121_20r_EW1]?  
Accessing tftp://172.20.58.78/cat4000-ios-promupgrade-121_20r_EW1...

!!!!!!!!!!!!!!!!!!!! 
[OK - 455620 bytes] 

455620 bytes copied in 2.644 secs (172322 bytes/sec) 
Switch#

Step 5 Use the no boot system flash bootflash:file_name command to clear all BOOT variable commands in the configuration file. In this example, the BOOT variable was set to boot the image cat4000-i5s-mz.121-19.EW1.bin from bootflash:

Switch# configure terminal

Switch(config)# no boot system flash bootflash:cat4000-i5s-mz.121-19.EW1.bin

Switch(config)# exit

Switch# write

Building configuration...

Compressed configuration from 3641 to 1244 bytes [OK]

Switch# 

Use the boot system flash bootflash:file_name command to set the BOOT variable. You will 
use two BOOT commands: one to upgrade the ROMMON and a second to load the Cisco IOS 
software image after the ROMMON upgrade is complete. Notice the order of the BOOT 
variables in the example below. At bootup the first BOOT variable command upgrades the 
ROMMON. When the upgrade is complete the supervisor engine will autoboot, and the second 
BOOT variable command will load the Cisco IOS software image specified by the second BOOT 
command.

Note The config-register must be set to autoboot.

---

In this example, we assume that the console port baud rate is set to 9600 bps and that the 
config-register is set to 0x0102.

Use the config-register command to autoboot using image(s) specified by the BOOT variable. 
Configure the BOOT variable to upgrade the ROMMON and then autoboot the IOS image after 
the ROMMON upgrade is complete. In this example, we are upgrading the ROMMON to version 
12.1(20r)EW1. After the ROMMON upgrade is complete, the supervisor engine will boot Cisco 
IOS software Release 12.1(20)EW1.

Switch(config)# config-register 0x0102

Switch(config)# exit

Switch# write

Step 6 Use the show bootvar command to verify the boot string. The BOOT variable in this example will first run the PROM upgrade to upgrade ROMMON. Then, the upgrade software will reload and the supervisor engine will load the Cisco IOS software image.

Switch# sh bootvar

BOOT variable = bootflash:cat4000-ios-promupgrade-121_20r_EW1,1;bootflash:cat400

0-i9s-mz.121-20.EW1,1

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist

Configuration register is 0x2102

Step 7 Run the PROM upgrade program by issuing the reload command. Issuing this command will terminate your Telnet session.

---

Caution Verify the boot string in step 6. No intervention is necessary to complete the upgrade. To ensure a successful upgrade, do not interrupt the upgrade process. Do not perform a reset, power cycle, or OIR of the supervisor engine until the upgrade is complete.

---

The following example shows the console port output from a successful ROMMON upgrade followed by a system reset. Your Telnet session is disconnected during the ROMMON upgrade, so you will not see this output. This step could take 2-3 minutes to complete. You will need to reconnect your Telnet session after 2-3 minutes when the Cisco IOS software image and the interfaces are loaded.

The ROMMON has now been upgraded.

See the "Upgrading the Cisco IOS Software" section for instructions on how to upgrade the Cisco IOS software on your switch.

Upgrading the Cisco IOS Software

---

Caution To avoid actions that might make your system unable to boot, please read this entire section before starting the upgrade.

---

Before you proceed, observe the following rules for hostname:

•Do not expect case to be preserved

Uppercase and lowercase characters look the same to many internet software applications. It may seem appropriate to capitalize a name the same way you might do in English, but conventions dictate that computer names appear all lowercase. For more information, refer to RFC 1178, Choosing a Name for Your Computer.

•Must start with a letter and end with a letter or digit.

•Interior characters can only be letters, digits, and hyphens; periods and underscores not allowed.

•Names must be 63 characters or fewer; hostname of fewer than 10 characters is recommended.

•On most systems, a field of 30 characters is used for the host name and the prompt in the CLI. Longer configuration mode prompts may be truncated.

To upgrade the Cisco IOS software on your Catalyst 4500 series switch, use this procedure:

---

Step 1 Download Cisco IOS Release 12.1(20)EW from Cisco.com, and place the image on a TFTP server in a directory that is accessible from the supervisor engine that is upgraded.

Step 2 Use the dir bootflash: command to ensure that there is sufficient space in Flash memory to store the promupgrade image. If there is insufficient space, delete one or more images, and then enter the squeeze bootflash: command to reclaim the space.

If you are using a CompactFlash card, use slot0: instead of bootflash.

Step 3 Download the software image into Flash memory using the copy tftp command.

The following example shows how to download the Cisco IOS software image cat4000-is-mz.121-12c.EW from the remote host 172.20.58.78 to bootflash:

Switch# copy tftp: bootflash:

Address or name of remote host [172.20.58.78]? 

Source filename [cat4000-is-mz121_12c.EW]?

Destination filename [cat4000-is-mz.121-12c.EW]?

Step 4 Use the no boot system flash bootflash:file_name command to clear the cat4000-is-mz.121-8a.EW file and to save the BOOT variable.

The following example shows how to clear the BOOT variable:

Switch# configure terminal

Switch(config)# no boot system flash bootflash:cat4000-is-mz.121-8a.EW

Switch(config)# exit

Switch# write

Step 5 Use the boot system flash command to add the Cisco IOS software image to the BOOT variable.

The following example shows how to add the cat4000-is-mz.121-12c.EW image to the BOOT variable:

Switch# configure terminal

Switch(config)# boot system flash bootflash:cat4000-is-mz.121-12c.EW 

Switch(config)# exit

Switch# write

Step 6 Use the config-register command to set the configuration register to 0x2102.

The following example show how to set the second least significant bit in the configuration register:

Switch# configure terminal

Switch(config)# config-register 0x2102

Switch(config)# exit

Switch# write

Building configuration...

Compressed configuration from 3723 to 1312 bytes [OK]

Step 7 Enter the reload command to reset the switch and load the software.

---

Caution No intervention is necessary to complete the upgrade. To ensure a successful upgrade, do not interrupt the upgrade process by performing a reset, power cycle, or OIR of the supervisor, for at least five minutes.

---

The following example shows the output from a successful upgrade followed by a system reset:

Limitations and Restrictions

These sections list the limitations and restrictions for the current release of Cisco IOS software on the Catalyst 4500 series switch.

All Supervisor Engines

•When you enter the permit any any ? command you will observe the octal option, which is unsupported in Cisco IOS Release 12.2(52)SG.

CSCsy31324

•A Span destination of fa1 is not supported.

For Supervisor Engines II+Plus through V-10GE

•For the IP Unnumbered feature, the following are not supported:

–Dynamic routing protocols

–HSRP/VRRP

–Static ARP

–Unnumbered interface and numbered interface in different VRFs

•For WCCP version 2, the following are not supported:

–GRE encapsulation forwarding method

–Hash bucket based assignment method

–Redirection on an egress interface (redirection out)

–Redirect-list ACL

•For IPX software routing, the following are not supported:

–NHRP (Next Hop Resolution Protocol)

–NLSP

–Jumbo Frames

•For AppleTalk software routing, the following are not supported:

–AURP

–AppleTalk Control Protocol for PPP

–Jumbo Frames

–EIGRP

•For the NetFlow feature, the following limitations apply:

–NetFlow will not account for control packets, packets that encountered link-level errors, and ARP/RARP packets.

–The software cache for NetFlow is fixed, users cannot change the size.

–The statistical distribution row that displays the distribution across various packet sizes is not available.

•For the PBR feature, the following limitations apply:

–Packet length-based matching policies are not supported.

–IP Precedence, TOS and Qos groups are fixed.

–ACL/Route-map statistics are not updated.

•IGRP is not supported (use EIGRP instead).

•The MAC address table is cleared when you switch between supervisor engines if either the 802.1s or 802.1w Spanning Tree Protocol is configured. To minimize address clearing and subsequent packet flooding, configure the edge ports as spanning-tree portfast and the link type as
spanning-tree link-type point-to-point.

•While running NSF and IS-IS IETF mode, if you enter the issu runversion command within 5 minutes of entering the issu loadversion command, packet loss may occur during an ISSU upgrade.

Workaround: Configure the NSF interval timer to 0 minutes, or delay entering the issu runversion command until the NSF interval timer expires and NSF restarts.

•Routes may not be properly redistributed from one routing protocol to another when NSF is enabled on the switch. The success of the redistribution depends on the order in which the routing protocols converge after an NSF switchover.

Workaround: None.

•IP classful routing is not supported; do not use the no ip classless command; it will have no effect because only classless routing is supported. The ip classless command is not supported because classless routing is enabled by default.

•The Catalyst 4510R switch does not support Supervisor Engines II-Plus, III, IV, and II-Plus-10GE. Installing an unsupported supervisor engine causes unpredictable hardware behavior that cannot be controlled by the software. Using an unsupported supervisor engine in a redundant slot might cause a supported supervisor engine in the other slot to malfunction.

•Supervisor Engine II-Plus cannot read a CompactFlash card formatted by Supervisor Engine III or Supervisor Engine IV in a prior release.

•Catalyst 4500 supervisor engines will not be properly initialized if the VLAN configuration in the startup file does not match the information stored in the VLAN database file. This situation might occur if a backup configuration file was used.

•A Layer 2 LACP channel cannot be configured with the spanning tree PortFast feature.

•Netbooting using a boot loader image is not supported. See the "Troubleshooting" section for alternatives.

•You cannot downgrade to Cisco IOS Release 12.1(8a)EW1 after running Release 12.1(13)EW (or higher). If you need to downgrade, contact your TAC representative for further instructions, and mention caveat CSCdz59058.

•Observe the following standard Cisco IOS software behavior when deploying redundant supervisor engines in a Catalyst 4507R chassis: While the startup configuration file is being parsed, the configuration file is not applied to hardware that does not exist.

For example, if the active supervisor engine is in slot 1, and you have configured interface Gi1/1, the supervisor engine in slot 2 becomes active if you remove the active supervisor engine from the chassis. In addition, while the startup configuration file is being parsed, you will receive an error message indicating that interface Gi1/1 is no longer present. This behavior is correct. When the formerly active supervisor engine is reinserted into slot 1, there is no configuration for interface Gi1/1.

This situation does not occur when both supervisor engines are present in the chassis.

Workaround: Copy the startup configuration file into the running configuration:

Switch# copy startup-config running-config

•An unsupported default CLI for mobile IP is displayed in the HSRP configuration. Although this CLI will not damage your system, you might want to remove it to avoid confusion.

Workaround: Display the configuration with the show standby command, then remove the CLI. Here is an example of the show standby GigabitEthernet1/1 command output:

switch(config)# interface g1/1

switch(config)# no standby 0 name (0 is hsrp group number)

•For HSRP preempt delay to function consistently, you must use the standby delay minimum command. Be sure to set the delay to more than 1 hello interval, which ensures that a hello is received before HSRP leaves the initiate state.

Use the standby delay reload option if the router is rebooting after reloading the image.

•When you attempt to run OSPF between a Cisco router and a third-party router, the two interfaces might get stuck in the Exstart/Exchange state. This problem occurs when the maximum transmission unit (MTU) settings for neighboring router interfaces do not match. If the router with the higher MTU sends a packet larger than the MTU set on the neighboring router, the neighboring router ignores the packet.

Workaround: Because the problem is caused by mismatched MTUs, you should change the MTU on either router to match the other's MTU.

•You can run .1q-in-.1q packet passthrough with a Supervisor Engine III and a Supervisor Engine IV, but you can run only .1q-in-.1q encapsulation with a Supervisor Engine II+10GE, Supervisor Engine V, and Supervisor Engine V-10GE.

•For PVST and Catalyst 4500 E-Series switch VLAN, Cisco IOS Release 12.1(13)EW supports a maximum of 3000 spanning tree port instances. If you want to use more instances, use MST rather than PVST.

•Only ports 1 and 2 on the WS-X4418-GB module and ports 13 and 14 on the WS-X4412-2GB-T module can be set as ISL trunks.

•If an original packet is dropped due to transmit queue shaping or sharing configurations, a SPAN packet copy can still be transmitted on the SPAN port.

•For all software releases, do not use over 100,000 routes.

•All software releases support a maximum of 16,000 IGMP snooping group entries.

•Use the no ip unreachables command on all interfaces with ACLs configured for performance reasons.

•Layer 3 path load-balancing metrics are not supported in Cisco IOS Releases 12.1(8a)EW, 12.1(11b)EW, 12.1(12c)EW, 12.1(13)EW, 12.1(19)EW, and 12.1(20)EW. (CSCdv10578)

•The threshold for the Dynamic ARP Inspection err-disable function is set to 15 ARP packets per second per interface. You should adjust this threshold depending on the network configuration. The CPU should not receive DHCP packets at a sustained rate greater than 1000 pps.

•A limited number of ACL bindings are dynamically installed by the IP source guard feature on a Catalyst 4500 series switch Supervisor Engine II-Plus. To take full advantage of the IP source guard feature, you should use Supervisor Engine IV.

•If you first configure an IP address or IPv6 address on a Layer 3 port, then change the Layer 3 port to a Layer 2 port with the switchport command, and finally change it back to a Layer 3 port, the original IP/IPv6 address is lost.

•By default, IPv6 is not enabled. To route IPv6, you must enter the IPv6 unicast-routing command. If you plan to use IPv6 multicast routing, use the IPv6 multicast-routing command.

•By default, CEF is not enabled for IPv6 (after IPv6 unicast routing is enabled). To prevent IPv6 traffic from being process-switched, use the IPv6 cef command.

•Multicast sources in community VLANs are not supported.

•Two-way community VLANs are not supported.

•Voice VLANs are not supported on community VLAN host interfaces.

•Private VLAN trunks do not carry community VLANs.

•When you use private VLANs on the WS-4516 module, old ARP entries will not tim eout of the ARP cache if you do not manually clear the entry. This event has no affect on production.

•Compact flash formatted in Cisco IOS Release 12.2(20)EW should be reformatted in Release 12.2(25)EW on both Supervisor Engine V-10GE and non-Supervisor V-10GE systems. Compact flash formatted on any other release does not need to be reformatted on non-Supervisor Engine V-10GE systems.

•In a redundant system, do not remove and reinsert the standby supervisor engine while the active supervisor engine is booting up. Doing so may cause a failure in the online diagnostics test.

Workaround: Remove and reinsert the standby supervisor engine after the active supervisor engine boots. (CSCsa66509)

•When used in conjunction with a 10-slot chassis, Supervisor Engine V only supports the
Catalyst 4500 series two-port Gigabit Ethernet line card (WS-X4302-GB) in the 10th slot.

•The maximum number of unique private VLAN pairs supported by the
switchport private-vlan mapping trunk command is 500. For example, one thousand secondary VLANs could map to one primary VLAN, or one thousand secondary VLANs could map one to one to one thousand primary VLANs.

•Support for PoE depends on the use of line cards and power supplies that support PoE.

PoE switching modules:

–WS-X4148-RJ45V

–WS-X4224-RJ45V

–WS-X4248-RJ45V

–WS-X4248-RJ21V

–WS-X4524-GB-RJ45V

–WS-X4548-GB-RJ45V

–'WS-X4548-GB-RJ45V+

PoE-enabled power supplies:

–PWR-C45-1300ACV

–PWR-C45-1400DC

–PWR-C4K-2800AC

–PWR-C45-1400AC

–PWR-C45-1300ACV

–'PWR-C45-6000ACV'

•The maximum number of mappings for configuring PVLAN promiscuous trunk ports is 500 primary VLANs to 500 secondary VLANs.

•The 802.1X inaccessible authentication bypass feature is not supported with the NAC LAN port IP feature.

•Changes to the console speed in line console 0 configuration mode do not affect console speed in ROMMON. To apply the same console speed in ROMMON, use the confreg ROMMON utility.

•Supervisor Engine II-Plus does not support compact flashes formatted by an Cisco IOS image prior to Cisco IOS Release 12.2(19)EW.

•If a Catalyst 4500 series switch requests information from the Cisco Secure Access Control Server (ACS) and the message exchange times out because the server does not respond, a message similar to following appears:

00:02:57:
