Open and Resolved Caveats in Software Release 7.6(17)

LACP, which is defined in IEEE 802.3ad, allows Cisco switches to manage Ethernet channeling with

devices that conform to 802.3ad. Prior to software release 7.1(1), Port Aggregation Control Protocol

(PAgP) was available. PAgP is a Cisco-proprietary protocol that can be run only on Cisco switches

and those switches released by licensed vendors.

• IEEE 802.1w rapid reconfiguration of spanning tree

Provides for the rapid reconvergence of the spanning tree after the failure of any link in a bridged

environment.

• PortFast on trunk ports

Allows PortFast to be configured for trunk or channel ports. On link up, the port immediately

transitions into spanning tree forwarding mode, bypassing listening and learning states, and

bypassing DTP, PAgP, and 802.3ad protocols.

• MAC address notification

The switch will report all learned and forgotten MAC addresses using SNMP traps.

• Multicast MAC address filtering

Allows an administrator to filter incoming traffic and block specified multicast MAC addresses on

specified ports, including IGMP control traffic and multicast data traffic. Multicast MAC address

filtering is not dependent on VLANs.

• Support for the following MIBs:

–

CISCO-ENTITY-FRU-CONTROL-MIB

–

CISCO-ENVMON-MIB

–

IEEE8021-PAE-MIB

Open and Resolved Caveats in Software Release 7.6(17)

These sections describe the open and resolved caveats in supervisor engine software release 7.6(17):

• Open Caveats in Software Release 7.6(17), page 18

• Resolved Caveats in Software Release 7.6(17), page 18

Open Caveats in Software Release 7.6(17)

There are no open caveats in software release 7.6(17).

Resolved Caveats in Software Release 7.6(17)

These caveats are resolved in software release 7.6(17):

• The switch fails to return the complete Fully Qualified Domain Name (FQDN). The switch returns

just the hostname and the domain is appended to the snmpset. When a management application reads

the name it sees the hostname as being different then the running config. The mangement application

then attempts to set the name by various means and starts a loop.

Workaround: Specify the complete FQDN on the switch entering the set system name

nms-2948G.sys.etc command and then on the NMS enter the snmpwalk -c public nms-2948G

sysName command. This issue is resolved in release 7.6(17). (CSCsd37685)
