I'd start with the basics. Does A have B's correct MAC address in it's
ARP table, and vice versa? Do the CAM tables look correct for these two
devices on all switches? Anything in the logs involving spanning tree
or mac address changes/flaps? I think (not positive about it though)
that you can see how long a MAC address has been associated with a port;
are they aging correctly?

Subject: Re: Intermittent Ping Problem
Greetings Ted,
How intermittent is this?
I have seen similar issues on a few 4006's.
Could you elaborate on your 4006 chassis config, maybe post a 'sh
mod'?
Thanx,
~M

I'm having a problem with intermittent connectivity as
follows...:
VL4 Trunk VL4
User1--->Cat6509/MSFC<----->Cat4006#2--User2
User1 can ping successfully for several minutes. Then
cannot. Sometimes I can get user1 to ping successfully
if I go to User2 and ping the other way. Trunks
contain VL4 and a couple of others.
Cat6509 OS = 7.3(1)
Cat 6509 MSFC IOS = 12.1(8b)E13
Cat4006 OS = 6.4(8)
Any help would be greatly appreciated.
