http://www.cisco.com/en/US/docs/ios/12_2s/release/notes/122Srn.html

Universal Boot Loader Image

A new supervisor engine contains one of the following initial software images:

  • Cisco IOS software
  • Catalyst operating system software
  • Universal Boot Loader (UBL) software

The UBL software is a minimal network-aware image that can download and install either a Cisco IOS image or a Catalyst operating system image from a running active supervisor engine in the same chassis.

When newly installed as a standby supervisor engine in a redundant application, a supervisor engine running the UBL software automatically attempts to copy the image of the running active supervisor engine in the same chassis. This feature requires the active supervisor engine to be running either Cisco IOS software Release 12.2SXH or later, or Catalyst operating system software Release 8.6(1) or later.


Note When a standby supervisor engine copies a Catalyst operating system software image using UBL, the downloaded image will not include the Multilayer Switch Feature Card (MSFC) software. A Cisco IOS software image that is downloaded using UBL will include the MSFC software.


FPD Image Packages


Note • Field Programmable Device (FPD) image packages were first introduced on the Catalyst 6500 series switches and Cisco 7600 series routers in Release 12.2(18)SXE.

  • FPD image packages update FPD images. If a discrepancy exists between an FPD image and the Cisco IOS image, the module that has the FPD discrepancy is deactivated until the discrepancy is resolved.


 

These sections describe FPD packages:

FPD-Image Dependant Modules

These modules use FPD images:

  • Shared Port Adapter (SPA) Interface Processors (SIPs)
  • Shared Port Adapters

Cisco IOS Software Modularity


Note • Release 12.2(33)SXJ and later releases do not support Cisco IOS Software Modularity.

  • With redundant supervisor engines, eFSU upgrade from a Cisco IOS Software Modularity image to a Release 12.2(33)SXJ image might result in a significant delay before the switch becomes active; the switch will be in the RPR redundancy mode.


 

These sections describe Cisco IOS Software Modularity:

http://www.cisco.com/en/US/docs/ios/12_4t/netmgmt/configuration/guide/t_eemo.html

Cisco IOS Software Modularity Unsupported Features

Release 12.2(33)SXI4 and later releases do not support Cisco IOS Software Load Balancing (SLB) with Cisco IOS Modularity images.

See the Cisco IOS Software Modularity Command Reference Introduction ” for detailed information about specific commands that are not supported in Cisco IOS Software Modularity images.

Troubleshooting

These sections describes troubleshooting guidelines for the Catalyst 6500 series switch configuration:


Note To attempt recovery from MSFC ROMMON, enter the confreg 0x2102 and reset ROMMON commands.


System Troubleshooting

This section contains troubleshooting guidelines for system-level problems:

  • When the system is booting and running power-on diagnostics, do not reset the switch.
  • After you initiate a switchover from the active supervisor engine to the redundant supervisor engine, or when you insert a redundant supervisor engine in an operating switch, always wait until the supervisor engines have synchronized and all modules are online before you remove or insert modules or supervisor engines or perform another switchover.
  • If you have an interface whose speed is set to auto connected to another interface whose speed is set to a fixed value, configure the interface whose speed is set to a fixed value for half duplex. Alternately, you can configure both interfaces to a fixed-value speed and full duplex.

Module Troubleshooting

This section contains troubleshooting guidelines for module problems:

  • When you hot insert a module into a chassis, be sure to use the ejector levers on the front of the module to seat the backplane pins properly. Inserting a module without using the ejector levers might cause the supervisor engine to display incorrect messages about the module. For module installation instructions, refer to the Catalyst 6500 Series Module Installation Guide .
  • Whenever you connect an interface that has duplex set to autonegotiate to an end station or another networking device, make sure that the other device is configured for autonegotiation as well. If the other device is not set to autonegotiate, the autonegotiating port will remain in half-duplex mode, which can cause a duplex mismatch resulting in packet loss, late collisions, and line errors on the link.

VLAN Troubleshooting


Note Catalyst 6500 series switches do not support ISL-encapsulated Token Ring frames. To support trunked Token Ring traffic in your network, make trunk connections directly between switches that support ISL-encapsulated Token Ring frames. When a Catalyst 6500 series switch is configured as a VTP server, you can configure Token Ring VLANs from the switch.


Although DTP is a point-to-point protocol, some internetworking devices might forward DTP frames. To avoid connectivity problems that might be caused by a switch acting on these forwarded DTP frames, do the following:

  • For interfaces connected to devices that do not support DTP, in which trunking is not currently being used, configure interfaces with the switchport mode access command, which puts the interface into access mode and sends no DTP frames.
  • When manually enabling trunking on a link to devices that do not support DTP, use the switchport nonegotiate and switchport mode trunk commands, which puts the interface into trunking mode without sending DTP frames.

Spanning Tree Troubleshooting

The Spanning Tree Protocol (STP) blocks certain ports to prevent physical loops in a redundant topology. On a blocked port, switches receive spanning tree bridge protocol data units (BPDUs) periodically from neighboring switches. You can configure the frequency with which BPDUs are received by entering the spanning-tree vlan vlan_ID hello-time command (the default frequency is set to 2 seconds). If a switch does not receive a BPDU in the time period defined by the spanning-tree vlan vlan_ID max-age command (20 seconds by default), the blocked port transitions to the listening state, the learning state, and to the forwarding state. As it transitions, the switch waits for the time period specified by the spanning-tree vlan vlan_ID forward-time command (15 seconds by default) in each of these intermediate states. If a blocked spanning tree interface does not receive BPDUs from its neighbor within 50 seconds, it moves into the forwarding state.


Note We do not recommend using the UplinkFast feature on switches with more than 20 active VLANs. The convergence time might be unacceptably long with more than 20 active VLANs.


To debug STP problems, follow these guidelines:

  • The show vlan virtual-port command displays the number of virtual interfaces.
  • These maximum numbers of virtual interfaces are supported:

 

Per-switch limits:
MST
RPVST+
PVST+
  • These per-switch limits apply to the following:

Release 12.2(33)SXI and later releases

Supervisor Engine 720-10GE

Supervisor Engine 720

100,000 total

12,000 total

15,000 total

Note Messages with the per-switch limits from earlier releases are still displayed in Release 12.2(33)SXI. Messages for the per-switch limits in effect in Release 12.2(33)SXI are displayed in Release 12.2(33)SXI1 and later releases. (CSCsx62912)

  • All other releases and supervisor engines:

50,000 total

10,000 total

13,000 total

 

Per-module limits:

6,000

1,800

1,800

Note

  • In Release 12.2(33)SXI1 and later releases, these limits do not apply to WS-X67xx and WS-X65xx switching modules. (CSCsu30263)
  • 10/100 Mb and 100 Mbps switching modules support a maximum of 1,200 logical interfaces per module

Note Cisco IOS software displays a message if you exceed the maximum number of virtual interfaces.


  • After a switchover from the active to the redundant supervisor engine, the ports on the redundant supervisor engine take longer to come up than other ports.
  • Record all spanning tree-blocked ports in each switch in your network. For each of the spanning tree-blocked ports, record the output of the show interface command. Check to see if the port has registered many alignment, FCS, or any other type of line errors. If these errors are incrementing continuously, the port might drop input BPDUs. If the input queue counter is incrementing continuously, the port is losing input packets because of a lack of receive buffers. This problem can also cause the port to drop incoming BPDUs.
  • On a blocked spanning tree port, check the duplex configuration to ensure that the port duplex is set to the same type as the port of its neighboring device.
  • On trunks, make sure that the trunk configuration is set properly on both sides of the link.
  • On trunks, if the neighboring device supports it, set duplex to full on both sides of the link to prevent any collisions under heavy traffic conditions.
