Switching

I ran into something wierd that baffles me, can anyone guess what I flubbed up?

 

So I have an HP Switch connected to a Juniper Stack (two ex4300's) via 4 links.

 

I have two going to port 46 and 47 on both units, so esentually its

 

HP(port45) to Juniper Switch 1 (port 46)

HP(port46) to Juniper Switch 1 (port 47)

HP(port47) to Juniper Switch 2 (port 46)

HP(port48) to Juniper Switch 2 (Port 47)

 

lldp is enabled everywhere:

 

protocols {
lldp {
interface all;
}

 

and I even tried putting one of the ports in the other switch in the stack in the default vlan 

 

ge-1/0/47 {
unit 0 {
family ethernet-switching {
vlan {
members default;
}
storm-control default;
}
}
}

 

but no matter what the output is always the following. I know its stacked but it doesn't seem to care about the other two interfaces. I'm kind of lost here, shouldn't it show all 4?

 

{master:0}

expecting also, but not there

ge-1/0/46 - 00:15:60:23:94:00 45 ProCurve Switch 2650
ge-1/0/47 - 00:15:60:23:94:00 46 ProCurve Switch 2650

Hey, try this out :

switch# set virtual-chassis no-split-detection

if not , please provide us the configuration .

thanks! Well that didn't work (or at least didn't appear to). I attatched the config, which is clean with the exception of things that I added to try to help lldp along. Its a test setup currently so its pretty bare bones. The HP only has default vlan 1, no configuration (other than spantree being enabled)

 

I am noticing that one of the interfaces ge-1/0/47 is showing up as an interface because as I understand it Juniper will not recognize ports off the master until they are assigned to a VLAN? Its showing up as a stack interface at least.

It's probably being blocked by spanning tree.  Try running this on the EX stack:

 

show spanning-tree interface

 

You'll probably see the one showing FWD and the other one showing BLK

hm.. ok lemme try ... This is what I got.

 

root> show spanning-tree interface

(-snipped-)

ge-0/0/45 128:535 128:535 32768.88a25ec89240 200000000 BLK DIS
ge-0/0/46 128:536 128:45 0.001560239400 200000 FWD ROOT
ge-0/0/47 128:537 128:46 0.001560239400 200000 BLK ALT
ge-1/0/47 128:547 128:48 0.001560239400 200000 BLK ALT

 

I'm guessing though that it would show it in LLDP anyway, otherwise I would only see one neighbor with spanning tree going. I plan on making all four connections LAG eventually.

 

root> show lldp neighbors
Local Interface Parent Interface Chassis Id Port info System Name
ge-0/0/46 - 00:15:60:23:94:00 45 ProCurve Switch 2650
ge-0/0/47 - 00:15:60:23:94:00 46 ProCurve Switch 2650

 

I tried moving one connection in the stack to the master one and that one suddenly appeared in the LLDP neighbor table.. so I am fairly sure its something i'm missing that is stack related.

 

UPDATE:

not sure what I did entirely, but I got this to work. I cleared out config, restacked, made sure I was looking at the right port, and added the interface to the configuration since it was missing. I'm not thrilled in how when you add a switch to the stack it means nothing in the config really, but as soon as I included it in the configuration it worked as expected.

 

So the ports were ge/0/0/46 and ge/1/0/46 (ge-0/0/46 was showing up but not ge-1/0/46)

 

then I added the port manually

ge-1/0/46 {
    unit 0 {
        family ethernet-switching {
            vlan {
                members default;
            }
        }
    }
}

then did a commit syncronize, and that seemed to do the trick.

still unsure what I did wrong but ... oh well.. thanks for trying to help everyone!
