These commands start one-time, non-periodic ELRP packet transmission on the specified ports of the
VLAN using the specified count and interval. If any of these transmitted packets is returned, indicating
loopback detection, the ELRP client can perform a configured action such as logging a message in the
system log file or printing a log message to the console. There is no need to trap to the SNMP manager
for non-periodic requests.
To start periodic ELRP packet transmission on specified ports of a VLAN using a particular interval, use
one of the following commands:
configure elrp-client periodic <vlan_name> ports [<ports> | all] interval <sec> [log |
log-and-trap | trap]
This command starts periodic ELRP packet transmission on the specified ports of the VLAN using the
specified interval. If any of these transmitted packets is returned, indicating loopback detection, the
ELRP client can perform a configured action such as logging a message in the system log file and/or
sending a trap to the SNMP manager.
To disable a pending one-shot or periodic ELRP request for a specified VLAN use the following
command:
unconfigure elrp-client <vlan_name>
Displaying Standalone ELRP Information
To display summary ELRP information, use the following command:
show elrp
The following information about ELRP appears:
●
State of ELRP (enabled/disabled).
●
Clients registered with ELRP
●
ELRP packets transmitted
●
ELRP packets received

Using the Rescue Software Image—Modular Switches
Only
WARNING!
The rescue image completely re-initializes the system. All data residing on the switch is cleared, including
configuration files, policy files, and other system-related files. Use this feature only with the guidance of Extreme
Networks Technical Support.
The concept of a rescue software image was introduced in ExtremeWare XOS 11.1. The rescue software
image recovers a switch that does not boot up by initializing the internal compact flash and installing
the ExtremeWare XOS software on both primary and secondary images of the compact flash. To use the
