802.3ad between M5 & Cisco cat3750

Hello,

Anyone have an example of the Cat side of a 802.3ad link between a M5
and cat3550/3750? I have found plenty examples of the Juniper side
(pretty simple) but I can't seem to get the link to come up. All the
cisco examples include LACP which juniper doesn't support until JUNOS
6.1 (we're at 5.7R1.2)?

I thought it would be as simple as:

Juniper:

ge-0/0/0 {
description "gigE#1 to 3750";
gigether-options {
802.3ad ae0;
}
}

ae0 {
vlan-tagging;
aggregated-ether-options {
minimum-links 1;
}
unit 0 {
vlan-id 100;
family inet {
address 10.10.10.1/24;
}
}
}

Cisco:

interface GigabitEthernet1/0/27
description ge-0/0/0 on Juniper
switchport access vlan 100
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
channel-group 1 mode on

Thanks,
Jason

with this configuration in the cisco side is ok for me (802.1q +
802.3ad) :

interface Port-channel1
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
!
interface GigabitEthernet1/1
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
channel-group 1 mode active
channel-protocol lacp

Hello,

What version of JUNOS are you running? We're not using 802.1q for
anything besides this (I guess you -have- to use 802.1q tags when doing
802.3ad on a juniper) ..

Correct, an aggregated link must have "vlan-tagging" enabled.

FWIW, on a Foundry switch the configuration is as simple as "trunk
server e 1 to 2" to configure an aggregated link.

Did you try changing the native vlan on the cisco side? If memory serves me
right Cisco leaves vlan 1 untagged yet Juniper tags the default vlan. Not
sure this applies to .3ad's but thought it was worth mentioning.

Well, of course you have to do that too. The vlan-id's on the Juniper
match the configuration of the switch. In this particular case:

!
vlan 110 by port
tagged ethe 1 to 2
!
vlan 130 by port
tagged ethe 1 to 2
!

... and configure the appropriate units on interface ae0 on the Juniper.

So you didn't have to configure tagged vlans on the Foundry? What do you
have the vlan id set to on the juniper?
