BLADE OS 5.1 Application Guide

To view detailed information for a remote device, specify the Index number as found in the
summary. For example, in keeping with the sample summary, to list details for the first remote
device (with an Index value of 210), use the following command:
Time-to-Live for Received Information
Each remote device LLDP packet includes an expiration time. If the switch port does not receive an
LLDP update from the remote device before the time-to-live clock expires, the switch will consider
the remote information to be invalid, and will remove all associated information from the MIB.
Remote devices can also intentionally set their LLDP time-to-live to 0, indicating to the switch that
the LLDP information is invalid and should be immediately removed.
