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
