Trunking - 5412z to Cisco 4500

I need to set up trunking between a cisco 4500 switch and a Procurve 5412Z.
I am using a single mode fiber linking a cisco ws-G5486 gbic on athe cisco to a ProCurve Gigabit-LX-LC Mini-GBIC (J4859C) on a 20-Port 10/100/1000 + 4-Port Mini-GBIC Module (J8705A.

I have trunking working between a cisco 4500 and a procurve 2600 PWR – any ideas as to why I cannot get this up?

Re: Trunking - 5412z to Cisco 4500

Hi

When you say on Cisco:

Switchport mode Trunk

It means on ALL other vendors:
Tagg all the vlans (you need to carry)

But Trunk (With all Vendors) means Etherchannel or Fast Etherchannel with Cisco.

So, for your case, if you just leave the port on the ProCurve 5400 switch UNTAGGED for Vlan1 (Native on Cisco), that should be fine.

But if you mean the link is not coming UP physically, then try the J4859B

Good Luck !!!

Hi, John !

Cisco means by Trunk port a switch port which is a member of VLANs configured on Cisco switch.

HP ProCurve call this VLAN trunk.
To make a switch port a member of any VLAN on HP ProCurve you should use the following commands:
vlan 7
tagged e24
vlan 8
tagged e24
...
etc for all required VLANs IDs

Good luck,
Dmitry

If you set up a port trunk (Port aggregation)
you should use the same commands to make your logical port (Port trunk) a member of all the required VLANs:

vlan 7
tagged trk1
vlan 8
tagged trk1
etc

Good luck,

Re: Trunking - 5412z to Cisco 4500

I did get the 5412 and the cisco trunking using SX gbicâ s in each J4858C on the procurve and a WS-G5484 on the cisco with a multimode cable â so I assume the logical port / trunk information on both is correct and I have some physical problem using LX -

I have tried 3 different LX gbics in each box and numerous (tested good) fiber jumpers with no success on getting a lx link up on the ports. -
