When you configure a port for 802.1ad UNI by entering the ethernet dot1ad uni s-port interface
configuration command and enter the l2protocol peer stp lldp command on a UNI-S port, STP and
LLDP protocols are not peered between both switches.
configuration command and enter the l2protocol peer stp lldp command on a UNI-S port, STP and
LLDP protocols are not peered between both switches.
The workaround, when you want to peer STP and LLDP between customer and provider edge
switches and to tunnel other Layer 2 protocols, is to use the ethernet dot1ad uni c-port interface
command to configure the service provider customer-facing port as a UNI-C port and not a UNI-S
port. By default on UNI-C ports, all Layer 2 protocols, including STP and LLDP are peered. For
protocols to be tunneled through the 802.1ad provider network, enter the l2protocol forward
command on the UNI-C port.

When an enhanced-services (ES) port is configured as a trunk port and the switch is using
VLAN-based EoMPLS, if the VLAN has been cleared from the trunks on the ES ports, packets
destined to IP addresses 224.0.0.xxx might not be sent over the EoMPLS tunnel.
VLAN-based EoMPLS, if the VLAN has been cleared from the trunks on the ES ports, packets
destined to IP addresses 224.0.0.xxx might not be sent over the EoMPLS tunnel.
The workaround is to allow the EoMPLS VLAN on the trunk on the ES ports.

When the status of a Resilient Ethernet Protocol (REP) primary edge port changes, for example,
because you enter the no shutdown interface configuration command, the switch sends duplicate
SNMP messages for the crepPortRoleChange trap.

A switch drops unicast traffic under these conditions:
–
The switch belongs to a Layer 2 ring.
–
More than 800 Mbps of multicast traffic is sent in both directions on the interface.
When multicast traffic is sent in one direction and unicast traffic is sent in another, unicast traffic is
dropped at the multicast traffic source port.
dropped at the multicast traffic source port.
The workaround is to apply a policy map so that the least significant traffic is discarded.

On a switch running Cisco IOS release 12.2(46)SE, the output of the show interfaces privileged
EXEC command shows 0 packets for port channel input and output rates.

The workaround is to reload the switch by entering the reload privileged EXEC command.

A switch can fail when an SNMP process attempts to configure dot1x authentication when it is
already configured.
