Documentation Updates

• CSCsv89005

A switch configured with class-based policies that are applied and active on at least one interface no

longer might reload or display CPU hog messages during SNMP polling for the ciscoCBQosMIB.

• CSCsv91358

When you have entered the vlan dot1q tag native global configuration command to configure a

switch to tag native VLAN frames on 802.1Q trunk ports, and you configure a new voice VLAN on

an access port, the MAC address of a connected PC is now correctly relearned.

• CSCsw30249

When a switch virtual interface (SVI) is configured as unnumbered and is pointing to a loopback

interface, the switch no longer fails when the SVI receives a packet.

• CSCsw45337

When LLDP is enabled and a voice VLAN is configured, the L2 Priority and DSCP Value fields in

the LLDP type, length, and value descriptions (TLVs) are now correctly marked to give the voice

traffic the correct DSCP and Layer 2 priority.

• CSCsw65548

Switch ports no longer attempt authentication at the interval configured for the port security timer

instead of the configured IEEE 802.1x timer.

Documentation Updates

This section provides updates to the product documentation:

• “Update to the Software Configuration Guide” section on page 18

• “System Messages Guide” section on page 19

Update to the Software Configuration Guide

This text was updated in the “Using IEEE 802.1x Authentication with Guest VLAN section of the

software configuration guide:

If the switch is trying to authorize an IEEE 802.1x-capable voice device and the AAA server is

unavailable, the authorization attempt fails, but the detection of the EAPOL packet is saved in the

EAPOL history. When the AAA server becomes available, the switch authorizes the voice device.

However, the switch no longer allows other devices access to the guest VLAN. To prevent this situation,

use one of these command sequences:

• Enter the dot1x guest-vlan supplicant global configuration command to allow access to the guest

VLAN.

• Enter the shutdown interface configuration command followed by the no shutdown interface

configuration command to restart the port.
