Configure 2 ports (trunk?) from core switch to IDF

I havea  core stack in our data center taht currently has 2 gig connections to an old HP switch in IDF1.  I had help configuring it a few years ago. I finally got myself another ICX 6450-48p to replace the HP.

 

I am trying to configure it so i can just swap out the HP. I know how to do most things including vlans.  I have never creataed a trunk group.  Which is confusing because i think cisco calls a trunk a port with mulple vlans?  reguardless.  I need to use 2 connectsions as 1 for throughput and redundency.

 

Here is my core config for my core two interfaces:

SSH@LOC-ICX6610-Core_Stack#show int eth 1/1/20 eth 2/1/20
GigabitEthernet1/1/20 is up, line protocol is up 
    Configured speed auto, actual 1Gbit, configured duplex fdx, actual fdx
  Configured mdi mode AUTO, actual MDI
  Member of 6 L2 VLANs, port is dual mode in Vlan 1, port state is FORWARDING
  BPDU guard is Disabled, ROOT protect is Disabled
  Link Error Dampening is Disabled
  STP configured to ON, priority is level0, mac-learning is enabled
  Flow Control is config enabled, oper enabled, negotiation disabled
  Mirror disabled, Monitor disabled
  Member of active trunk ports 1/1/20,2/1/20, primary port
  Member of configured trunk ports 1/1/20,2/1/20, primary port
  Port name is HP-2824_IDF1_Sw1
  Inter-Packet Gap (IPG) is 96 bit times
  MTU 1500 bytes, encapsulation ethernet
    Relay Agent Information option: Disabled

Re: Configure 2 ports (trunk?) from core switch to IDF

Yes Cisco uses the term "trunk" to pass multiple vlans over a single link.  Brocade uses a "Tag" in vlan configuration to include it on an interface.  Then you can "tag" multiple vlans across a single link.  However what your looking for is "port-aggregation"  or  "LAG"  which you can combine multiple physical ports to act as 1 interface.  Both Brocade and Cisco has the IEEE standard and their own flavor of this.  On your IDF it appear that you have ports 27-28 named "Trk1" aggregated together.  all you have to do per documentation is: 

 Create your "LAG"

device(config)#lag "test" dynamic id 1

 

Add ports to your "LAG"

device(config-lag-test)#ports ethernet 1/1/1 to 1/1/3

 

make a port primary

device(config-lag-test)#primary-port 1/1/1

 

then "Deploy" your LAG **this is a must**

 

you can do a "show lag" verify settings.

 

then when your in vlan configuration mode just "TAG" that VLAN to the Primary port of the LAG.  the rest of the ports (within the LAG) will be included.
