Hello, new to JunOS. Does a J-series router (J2350 in this case) support bonding ethernet interfaces to create Etherchannel/802.3ad links? This will link to Cat3750's. In IOS this would be port-channel X, then int foo; channel-group X.
Specifies a “bundle” of Gigabit Ethernet interfaces on this router with which to share traffic.
To use this feature, you must already have configured an aggregate Ethernet interface, by specifying the link number as a physical device and then associating a set of ports that have the same speed and are in full-duplex mode.
Actually 802.3ad is not supported on J-series. That screenshot is obviously from an M or T series router (can tell because interface shows ge-0/3/0). Likely the J-web info was taken from M & T docs as well. J-Series does not support aggregate interfaces.
That is interesting. On Jseries version of JUNOS (non Enhanced Services) the 802.3ad option is definitely not there. But I just checked on JUNOS with Enhanced Services and I do see the option there for gigE interfaces. Enhanced Services version supports the concept of reths which is part of JSRP configuration. Reth uses the aggregate interface infrastructure. But as I understood it we should not be supporting 802.3ad. I will need to check to see whether we officially support this on Enhanced Services or not.
It appears that beginning with JUNOS version 9.2, the J-Series does support link aggregation. But only with switching uPIMs (not the onboard ports) and only with Enhanced Services version. This is a new feature which was implemented just recently. Hope that answers this question.
By the way, not quite related but on some juniper documentation the onboard ports are mentioned as management ports, do these ports have any deficiencies performancewise or otherwise compared to gigabit ethernet modules?
I'm finding some information on MLPPP. Nothing specific to J-series T1 interfaces. ISP's will usually support MLPPP if requested. I will try it in the lab. Sorry to hijack the ethernet-bonding thread. Thanks.
