elrp-client on 5000 series?

Scott_Proctor — Mon, 03 Jul 2023 22:12:15 GMT

So we are putting a bunch of new Extreme 5520's in and we use ELRP to detect loop traffic. I want it to log-and-trap so that our ExtremeCloud IQ site engine can send me an alarm and I would typically input the following command:

configure elrp-client periodic <VLAN_Name> ports all interval 1 log-and-trap disable-port ingress duration 300

but when I do that and hit enter it takes it and I go back and check the config and all I get is:

configure elrp-client periodic vlan <VLAN_Name> ports all disable-port duration 300

Are the 5000 capable of log-and-trap? It let me autocomplete the command, but it's weird that I don't see it in the config now.

"log-and-trap" is the default when configuring ELRP ports (see the CLI output below), and therefore the config with "log-and-trap" is the equivalent of the config without having this sub-section added. That's why it's not showing up any differently.

I suggest testing the behavior and validating that the switch is in fact creating log messages and sending traps to the receiver.

5520-24W-SwitchEngine.6 # conf elrp-client periodic Default ports 2 <cr> Execute the command disable-port Disable port where looped PDU transmitted or received. interval Time Interval between 2 successive ELRP polls log Print polling result to system log log-and-trap Print polling result to system log and send SNMP trap (Default) remote-endpoints Include the remote endpoints, if any, in this VLAN (Only supported with software ELRP) trap Send SNMP trap
