The ePMP 4600 shows two radio interfaces in SNMP:
IF-MIB::ifDescr.1 = STRING: WLAN interface 1
IF-MIB::ifDescr.2 = STRING: WLAN interface 2
IF-MIB::ifDescr.3 = STRING: LAN interface 1
IF-MIB::ifDescr.4 = STRING: LAN interface 2
But, in the documentation and the web app I can only find any reference to the first one. The second radio interface has a distinct MAC address and shows as Up but does not have any nonzero counters in SNMP.
Can anyone explain what this is?
