Hi Robert,
If you are using Cisco 12000, Quad OC-3 line card, only one SAR pool of
512KB is assigned for all PVC by default. PVC with large PCR and SCR will
dominate the SAR pool. However, You can break the single SAR pool into 4
small 128KB SAR Pools.
For cisco 7500 series, you won't have the SAR pool problem.
e.g.
interface ATM0/0
sar txpool 4
!
interface ATM0/0.123
atm pvc 123 0 123 aal5snap 50 25 100
sar vc 123 txpool 1
!
Best Regards,
W.S. Chan

Subject: SAR DELAY
Anyone know the delay on a packet going through a SAR. I am experiencing a
delay of 80 ms on a 155 pipe end to end. No errors or anything which would
normally suggest delay. The only major delay item is the SAR, hence the
question. This ping packet is a normal packet size.
Thanks
