Release Notes

Release Notes for the Catalyst 2960-C and 2960-Plus Switches, Cisco IOS Release 15.2(3)E and Later

OL-32525-01

Limitations and Restrictions

The workaround is to choose compatible buffer sizes and threshold levels. (CSCea76893)

• When auto-QoS is enabled on the switch, priority queuing is not enabled. Instead, the switch uses

shaped round robin (SRR) as the queuing mechanism. The auto-QoS feature is designed on each

platform based on the feature set and hardware limitations, and the queuing mechanism supported

on each platform might be different. There is no workaround. (CSCee22591)

• If you configure a large number of input interface VLANs in a class map, a traceback message

similar to this might appear:

01:01:32: %BIT-4-OUTOFRANGE: bit 1321 is not in the expected range of 0 to 1024

There is no impact to switch functionality.

There is no workaround. (CSCtg32101)

RADIUS

• RADIUS change of authorization (COA) reauthorization is not supported on the critical auth VLAN.

There is no workaround. (CSCta05071)

Smart Install

• When upgrading switches in a stack, the director cannot send the correct image and configuration

to the stack if all switches in the stack do not start at the same time. A switch in the stack could then

receive an incorrect image or configuration.

The workaround is to use an on-demand upgrade to upgrade switches in a stack by entering the

vstack download config and vstack download image commands. (CSCta64962)

• When you upgrade a Smart Install director to Cisco IOS Release 12.2(55)SE but do not upgrade the

director configuration, the director cannot upgrade client switches.

When you upgrade the director to Cisco IOS Release 12.2(55)SE, the workaround is to also modify

the configuration to include all built-in, custom, and default groups. You should also configure the

tar image name instead of the image-list file name in the stored images. (CSCte07949)

• Backing up a Smart Install configuration could fail if the backup repository is a Windows server and

the backup file already exists in the server.

The workaround is to use the TFTP utility of another server instead of a Windows server or to

manually delete the existing backup file before backing up again. (CSCte53737)

• In a Smart Install network, when the director is connected between the client and the DHCP server

and the server has options configured for image and configuration, then the client does not receive

the image and configuration files sent by the DHCP server during an automatic upgrade. Instead the

files are overwritten by the director and the client receives the image and configuration that the

director sends.

Use one of these workarounds:

–

If client needs to upgrade using an image and configuration file configured in the DHCP server

options, you should remove the client from the Smart Install network during the upgrade.

–

In a network using Smart Install, you should not configure options for image and configuration

in the DHCP server. For clients to upgrade using Smart Install, you should configure product-id

specific image and configuration files in the director. (CSCte99366)
