These switches are not like the Procurves. They have a completely different language, and they do some things much, much better than Procurves, at least the older ones. And, they are a lot less expensive.
The A5120 does not use the same command set as the Procurve series. For example, when you first log in, use system to go into the configuration mode (instead of config) and to save a running configuration, use the save command (instead of write mem).
Following are some of the commands I have run across I need.
Got a couple of these and put them together with some modules and cables that made two 48 port switches into one 96 port. YEAH. Then, began setting up LACP on them so we would have fail over. I decided to use ports 2-whatever as LACP, and ports whatever-48 for IPMI. We'll see how it works.
First, port 1 is used for outside. Going to try an run some different virtual routers for that which have failover. Following is an example for setting up Port 2 on both switches as on LACP trunk. Since this will involve port 2 on switch 1 and 2, I decided to call it Aggregation Port 2, aka BAGG2.
Ports are named by switch, “something” and port number, separated by slashes (/), so I am creating BAGG2 with members
Meaning “Switch 1, Port 2” and “Switch 2, port 2”.
I'm also disabling access to vlan 1 (the default) and adding access to vlans 10 and 20. The descriptions are free form text; basically for the ports I'm just saying they are members of the bagg (bridge aggregation)
Following are the commands.
interface Bridge-Aggregation 2 description lacp port link-type trunk undo port trunk permit vlan 1 port trunk permit vlan 10 20 link-aggregation mode dynamic interface gig 1/0/2 port link-type trunk description bagg2 member 1 undo port trunk permit vlan 1 port trunk permit vlan 10 20 port link-aggregation group 2 interface gig 2/0/2 port link-type trunk description bagg2 member 2 undo port trunk permit vlan 1 port trunk permit vlan 10 20 port link-aggregation group 2 display link-aggregation summary
This command displays all LACP configurations. It will give some interesting information, ie the number of members (integers in columns 4 and 5) which confused me at first, until I realized it will show something different depending on the state of the members; unplugged, plugged but not up, up.
When no network cable connected, or there is no connection, the members will all be invalid (ie, in the fifth column)
BAGG2 D 0x8000, 0000-0000-0000 0 2 Shar
When connected but not configured (ie, powered down or trunk not yet configured on attached device), it will show one member active and one inactive.
BAGG2 D 0x8000, 0000-0000-0000 1 1 Shar
When operating correctly, powered up and the attached device is set up for LACP, both members will show up in the fourth column.
BAGG2 D 0x8000, 1cc1-de6f-e3f4 2 0 Shar
