EXOS Sharing master port not added to Agg Mbr

[Robert_Zdzieblo]

Can you MLAG different plateforms 450E and a 460?

Hi Tomasz,

There is nothing like media converter in between, it's direct MM link.

At the moment the lag seems to be OK (?):

code:

  * Slot-1 PPD22.3 # sh sharing
Load Sharing Monitor
Config    Current Agg     Min    Ld Share  Dist  Ld Share  Agg Link  Link Up
Master    Master  Control Active Algorithm Flags Group     Mbr State Transitions

                                  L2              3:26      Y     A       0

Here is "show lacp lag 1:26 detail" output:

code:

Due to the transient nature of the issue I am going to replace 10G modules and check the fiber link, although all DDMI data read from EXOS side is normal (?).

REGARDS, Robert

BTW on the topic list I see this as posted by Ted, and the teaser is about MLAG of X450e and X460 question... 

[Tomasz]

Hi Robert,

This behavior is most likely to occur when that port is connected to some port on the other side, that is not a part of partner's LACP group. Or maybe you have some media converter or other device in between, so EXOS/converter link is UP, but converter/S4 link is down?

Please let us know the version of EXOS firmware and two outputs might also be useful:

• show lacp lag 1:26 detail
• show lacp member-port 1:26 detail

How about lacp-related outputs on S4 side? There might be some reason.

Kind regards,
Tomasz

Thank You, Drew !

I re-posted my question again with slightly different title.
In fact, I was having problems sending the question form.
Beside, many links within new Hub site didn't work, especially those located in my profile.
