[cisco-voip] Cisco Emergency Responder on third-party switches

[Wilusz, Mike]

John,

We have an active deployment of CER with Juniper EX switches.  These switches support LLDP as well.  The only supported ERL mapping is via subnets.  In our building, we have 6 floors.  We divided each floor in half and gave it it's own voice subnet.  Therefore we have a total of 12 ERLs and this seems to work well, though not nearly as integrated as the Cisco switch/CDP router.

Does anybody have experience rolling out CER with third party switches, specifically Extreme x450 series? These switches support lldp but I am not sure if CER supports LLDP for ERL?

I am thinking about doing ERL by subnet, and dividing buildings into zones with their own subnets.

any advice?
