High Packet Drop and connection failure

See notes inband and below"

 

 

LTM-1 <> LTM-2 Fibre dual link -->> Does this fiber directly connect the two units or are they going through a switch? (HA subnet?)

 

In regard to these tests:

 

Around 10% packet drop:- --> very high but there may be something we are missing here.

 

LTM1 <> LTM2 --> Is this a direct fiber cable between each unit or are they going through the switch?

 

LTM1 <> Any Node sitting under 2960-1 --> Are you routing to the node or is the LTM directly on the same subnet (single leg or 802.1q)?

 

LTM2 <> Any Node sitting under 2960-2 -> Is this ping taking place over an HA subnet or internal vlan subnet from self-ip to self-ip?

 

 

 

There is no need to get rid of the channel configuration. This gives you physical layer redundancy. Temporarily though, it wouldn't hurt to just pull one cable from each channel to simplify the infrastructure. Singe links temporarily. VTP shouldn't have anything to do with this, although I have never been a big fan of it and always left it in transparent mode, but that's another discussion. The default for STP is passthrough although I usually disable it. Don't let my so-called best practices sway you, everyone has an opinion on it.

 

 

Leave the bridge id alone. It's just set high to keep it from becoming root. It shouldn't "match" anything unless you really know what you are doing. You're other assumptions are correct (9, 10).

 

 

As Nitass stated and as said before, let's focus on the problematic VS. In this case you mentioned the smtp vs. Take front and back dumps simultaneously and attempt to catch/find a "broken" connection. From there, we can analyze further.

 

 

Also, have you tried failing the LTMs over in case one is acting up?
