Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
an LLDP-MED endpoint, refer to “Displaying the Current Port Speed and
Duplex Configuration on a Switch Port” on page 13-76.
Syntax: show interfaces brief < port-list >
Includes port speed and duplex configuration in the
Mode
column of the resulting display.
Displaying Advertisements Currently in the Neighbors MIB. These
commands display the content of the inbound LLDP advertisements received
from other LLDP devices.
Syntax show lldp info remote-device [ port-list ]
Without the
[port-list]
option, this command 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 net­
work topology loop. Note that LLDP packets travel on links
that spanning-tree blocks for other traffic types.)
With the
[ port-list ]
option, this command 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, refer to Table 13-3 on page 13-45.
