Need some advice on setting up an ERC-1260 pair in HA configuration please.
All of our SIEM kit is running version 9.6.0
All ESM, ELM, and ACE appliances have been added to the primary ESM, it's just the ERC HA that we're struggling with.
The shared IP address is on our PROD network, and the unique IP addresses are on our MGMT network:
Shared IP on PROD network: x.x.92.1
ERC1 MGMT IP on MGMT network: x.x.116.7
ERC2 MGMT IP on MGMT network: x.x.116.8
Both are connected to the MGMT network via port 1 (the one closest to the IPMI port).
Both ERC have the above MGMT addresses configured in the LCD console.
Using the above MGMT addresses I can add the primary, and the secondary ERC, and save the config. But when I try and change the Shared IP field to the PROD address it hangs the console and eventually times out.
Both are connected to the PROD network via port 1 (the one closes to the IPMI port).
ERC1 has the PROD (shared) address configured in the LCD console.
ERC2 has the MGMT (unique) address configured in the LCD console.
I can add ERC1 using the shared address, but it fails when adding ERC2 using t's MGMT address.
I have confirmed SSH connectivity from the ESM to the ERC using both PROD and MGMT networks.
Do all 3 IP addresses need to be in the same vlan?
Any advice is very welcome.
