[c-nsp] Limits on dynamically learned MAC addresses per vlan

[Steven Pfister]

Yes, the limit was set to 200 at AT&T. They've bumped it up and everything seems to be happy now. 

Thanks to everyone who responded.... I thought I was going crazy... :-)

Steve, is that CSME link the managed ethernet product from ATT? If so, 
you may be hitting a limitation in that product where it only allows a 
set number of mac addresses. You said 'seems to be 200' as the number 
you can observe, and that sounds in line with what I know about it.

If so, you can confirm with your ATT account rep and either buy more mac 
address allocations, or (how it was intended to be used), establish your 
own l2vpn between the sites and eliminate the restriction entirely.

please report to the list if any of this is/is not helpful.

thanks.
