Wired Intelligent Edge

Hi,
We recently upgraded our analog PBX to IP PBX + IP Phones and we are having issues with computers not getting any connection when connected to IP Phone PC Port (passthrough), it is not that the PC not getting any DHCP, it's just 'Link Down'. Its only when we connect to Aruba switches, there is no issue mentioned when connecting to Cisco switch, IP Phone with its voice vlan and the PC Port with its data vlan. We spend some time looking at the Aruba switch configuration just to find out that data/voice vlans,qos,cdp,etc were configured properly.

Cisco

Aruba 2530-48-POE+

Cisco Catalyst 2960

Yep, we tried enabled poe pre standard too.. 

Hi ,

Could you share interface config :

sh run int (interface number )

sh power-over-ethernet (interface number )

sh lldp info local-device (interface number )

Thanks ,

Hi,

Info, both IP Phone + Desktop is connected to int1-2

-int1, IP Phone PC Port is auto-negotiate (default), PC Port status Link-Down

-int2, IP Phone PC Port is set manual to Full-Duplex 100Mbps, PC Port status Link-Up

Here goes the config for both interface ;

SW010ACCEDSBN# sh run int 1-2

Running configuration:

interface 1
tagged vlan 5
untagged vlan 4
exit
interface 2
tagged vlan 5
untagged vlan 4
exit
