(2)Checking port status

•Execute the show vlan command with "detail" parameter specified, and confirm that the port is Up. If the port is Down, see "3.4 Network Interface Communication Failure."

•Confirm that the port is in the Forwarding status. If the port is in the Blocking status, the reason is shown in parentheses. Check the operation status of the function causing the problem.

[Cause]

VLAN: VLAN is specified to suspended.

CH: Forwarding is suspended by link aggregation.

STP: Forwarding is suspended by spanning tree.

GSRP: Forwarding is suspended by GSRP.

dot1x: Forwarding is suspended by IEEE802.1X.

CNF: Forwarding is suspended due to inability of configuration setting.

AXRP: Forwarding is suspended by Ring Protocol.

(3) Checking MAC address table

(a) Checking MAC address learning status

•Execute the show mac-address-tablecommand to retrieve the information of the failed destination MAC address.

# show mac-address-table

•Take the action below according to the Type displayed.

[When Type displayed is Dynamic]

MAC address learning information may not be updated. Execute the clear mac-address-tablecommand to clear old information. The old information can be also cleared by sending frames from the destination system.

[When Type displayed is Static]

Check the forwarding destination port configured using configuration command mac-address-table static.

[When Type displayed is Snoop]
