ESM -> ERC SSH problem.

Hello all, need some advice on the following please.

We have a pair of ERC 1260 that are configured in HA.  They are configured as follows:

Eth0 - unique MGMT address (for comms to ESM and ELM)

Eth1 - shared MGMT address

Eth2 - shared PROD (to receive data from event sources)

Problem:

- ESM can SSH to primary ERC, but not secondary.

- Reboot secondary ERC.

- Can now SSH from ESM to secondary ERC, but cannot SSH from ESM to primary ERC.

- Reboot primary ERC.

- Can now SSH from ESM to primary ERC, but cannot SSH from ESM to secondary ERC.

- And repeat.  Whichever ERC is rebooted last, I can SSH to it from the ESM, but not the 'other' ERC.

As well as this pair, we have 3 other pairs of ERC 1260 that are configured in exactly the same way, and there are no problems with SSH connectivity to them from the ESM.

Re: ESM -> ERC SSH problem.

When you reboot an HA ERC, HA role maybe swapped. Try SSH tunnel through to the secondary ERC via ESM.

Could you please share the below screenshot -

- Receiver Information from Receiver Properties

- Network tab under Receiver Properties>Receiver configuration>Inerface>Network

- ifconfig from both the receivers
