Starts one-time, non-periodic ELRP packet transmission on the specified ports of the VLAN (Virtual LAN) using the specified count and interval.
| vlan_name | Specifies a VLAN name. |
| ports | Specifies the set of VLAN ports for packet transmission. |
| all | Specifies all ports of this VLAN for packet transmission. |
| sec | Specifies the interval (in seconds) between consecutive packet transmissions. The range is 1 to 600 seconds. The default is 1 second. |
| count | Specifies the number of times ELRP packets must be transmitted. The range is 1 to 255 times. The default is 3 times. |
| log | Specifies that a message should be logged in the system log file when ELRP packets are received back indicating detection of network loop, or no packets are received within the specified duration. |
| Specifies that a message should be printed to the console when ELRP packets are received back indicating detection of network loop, or no packets are received within the specified duration. | |
| print-and-log | Specifies that a message should be logged in the system log file and printed to the console when ELRP packets are received back indicating detection of network loop, or no packets are received within the specified duration. |
sec—The interval between consecutive packet transmissions is 1 second.
count—The number of times ELRP packets must be transmitted is 3.
This command starts 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 send a trap to the SNMP (Simple Network Management Protocol) manager for non-periodic requests.
Note
This command is backward compatible with Extreme Networks switches running ExtremeWare. If your network contains switches running only ExtremeXOS, you can also use the run elrp vlan_name {portsports} {intervalsec} {retrycount} to perform one-time ELRP packet transmission.
Use the configure elrp-client periodic command to configure periodic transmission of ELRP packets.
The ELRP client must be enabled globally in order for it to work on any VLANs. Use the enable elrp-client command to globally enable the ELRP client.
The ELRP client can be disabled globally so that none of the ELRP VLAN configurations take effect. Use the disable elrp-client command to globally disable the ELRP client.
The following example starts one-time, non-periodic ELRP packet transmission on all ports of the VLAN sales, uses the default interval and transmission times, and sends messages to the console:
configure elrp-client one-shot sales ports all interval 1 retry 3 print
This command was first available in ExtremeXOS 11.1.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X620, X690, X870 series switches.
