Release Notes for the Catalyst 3750 Switch Cisco IOS Release 12.1(14)EA1

OL-4215-01

Resolved Caveats

• CSCea02851

When you are in policy-map class configuration mode and configure an aggregate policer with the

police aggregate policy-map class configuration command, causing the number of aggregate

policers to exceed 63, the aggregate policer is no longer retained in the policy map.

• CSCea21883

Under some heavy load conditions with bridge groups and SPAN enabled (where the packets are

dropped at the port because of flooding), the %SUPQ-4-CPUHB_RECV_STARVE message no

longer appears. During this condition, the port output rate is no longer reduced to recover from the

condition.

• CSCea35481

An extended access list with permit or forward actions using Layer 4 information no longer

incorrectly forwards fragmented packets. All packets are correctly forwarded now.

• CSCea54285

You can now set the VTP mode to transparent (3) by using SNMP.

• CSCea67031

The switch no longer take several minutes to generate and optimize the forwarding rules after you

configure a complex VLAN map. For example, a complex VLAN map might contain multiple

sequences that use the same VLAN map ACL, where the individual ACL clauses include one or

more deny clauses (nonterminating–not the last deny). During the optimization process, the switch

now responds to commands.

• CSCea75726

When snooping is disabled and a spanning tree loop exists, incoming IGMP report and leave

messages no longer generate a storm of such messages in the network.

• CSCea86944

Gigabit Ethernet ports configured for RGMII mode (1/2, 5/6, 9/10, 13/14, 17/18, and 21/22) no

longer fail an internal loopback test during system startup on the Catalyst 3750G-24T and Catalyst

3750G-24TS switches.

• CSCea88723

A routed port that uses an IP ACL no longer filters packets incorrectly after an administrative

shutdown and restart. The problem previously occurred after the following sequence:

–

An IP ACL is applied to a routed port by using the ip access-group interface configuration

command.

–

The routed port is shut down by using the shutdown interface configuration command.

–

The ACL is modified or another interface is changed between routed port and switched port by

using the switchport and no switchport interface configuration commands.

–

The routed port is re-enabled by entering the no shutdown interface configuration command.

• CSCeb05555

The RSPAN feature no longer incorrectly spans all local link control packets with a destination

MAC address of 0100.0CCC.CCCC on trunk ports that carry the RSPAN VLAN. Therefore, trunk

ports carrying the RSPAN VLAN no longer combine control packets from RSPAN source ports with

normal local control packets. The following list describes problems that previously occurred with

selected protocols:

–

Cisco Discovery Protocol (CDP) could provide incorrect information. For example, CDP could

incorrectly list a neighbor switch that is actually a neighbor on the RSPAN source port.
