Requirements for a MAD switch

Hi All,

I have been reading VSF documentation for 5412R switches. It says to avoid split fabric issues in case VSF link goes down, it is recommended to have a third MAD switch and enable Multi Active Detection (MAD) on theVSF fabric.

 

My question is does MAD switch needs to be an Aruba/HPE switch or it can be any switch that supports LACP/LLDP?

Re: Requirements for a MAD switch

For LLDP-MAD the following must be supported by the neighbor switch:

- IP-address reachable from VSF
- LLDP
- SNMPv2
- LACP

 

VSF system performs a number of checks to verify if all requirements have been met. You can verfify with "show vsf lldp-mad parameters" the "MAD readiness status".


=> therefore there is no need for an Aruba/HPE switch if the above is supported.

Thanks. Also found it in the documentation later on.
