Viewing the current port speed and duplex configuration on a switch port

Syntax

show interfaces brief <port-list>

Includes port speed and duplex configuration in the Mode column of the resulting display.

Viewing advertisements currently in the neighbors MIB

Syntax

show lldp info remote-device<port-list>

Without the <port-list> option, provides a global list of the individual devices it has detected

by reading LLDP advertisements. Discovered devices are listed by the inbound port on which they

were discovered.

Multiple devices listed for a single port indicates that such devices are connected to the switch

through a hub.

Discovering the same device on multiple ports indicates that the remote device may be connected

to the switch in one of the following ways:

• Through different VLANS using separate links. (This applies to switches that use the same MAC

address for all configured VLANs.)

• Through different links in the same trunk.

• Through different links using the same VLAN. (In this case, spanning-tree should be invoked

to prevent a network topology loop. Note that LLDP packets travel on links that spanning-tree

blocks for other traffic types.)

With the <port-list> option, provides a listing of the LLDP data that the switch has detected in

advertisements received on the specified ports.

For descriptions of the various types of information displayed by these commands, see Table

6-4 (page 253).
