Hello GS, Mark

I hope all is well. To follow up Mark's question, what is the best URL for
the recommendations of the TX-ring size when doing QoS on ATM links?

Mark, if you are not performing QoS on the ATM interfaces then leaving the
TX-ring limit @ the default is the recommendation. If you are performing
QoS then the TX-ring limit should be adjusted in order for your QoS configs
to have affect...

I can not seem to find the URL I once saw with the recommended TX-ring
sizes.... anyone? TIA!

Andrew

Looking for other ways to tweak interfaces:

Rack1R1(config-if)#tx?
tx-ring-limit
Rack1R1(config-if)#tx-ring-limit 123
Rack1R1(config-if)#end
Rack1R1#sh run | b interface Serial0/0
interface Serial0/0
 no ip address
 encapsulation frame-relay
 tx-ring-limit 123
 tx-queue-limit 123

(note: tx-queue-limit is automagically added to the config)

I tried looking this up only to find some ATM-PA references that did not
clarify.
...Same commands (or lack thereof) appear to be true/available on ethernet,
etc...
I hope am clear in thinking this has nothing to do with the hold-queue in |
out command
(which defines the maximum # of input and output queues as I understand it)

That said, I am curious just what this does, if anything
And why we cannot do just a queue-limit?
(since that command does not exist??)
