I have two almost identical 3662 routers with HSSI card. "show buffers" shows me different buffers count for HSSI card on the routers. Those router that has lower value uses Normal particle pool more intensively and continuosly increases "throttle" counter on all interfaces. Those, that have higher value, almost don't use normal particle pool and don't have a problem with "throttle". Can I manage somehow the count of buffers allocated for HSSI card?
Public particle pools:
Normal buffers, 1548 bytes (total 768, permanent 768):
758 in free list (128 min, 1024 max allowed)
58010039 hits, 596861 misses, 93529 trims, 93529 created
Yes they do. "BAD" has 111616K/19456K; "GOOD" has 252928K/9216K.
Also "BAD" router has 12.1.14 version but "GOOD" has 12.0.5.T.XK1 version.
I have tried Bad router with 12.2 but it has the same problem. But when I installed 12.0.5.T.XK1 on the Bad router, it allocated 256 buffers for HSSI interface and stopped to use them from Normal particle pool. So the problem seems to be version related.
I wonder why newer versions has only 120 buffers alocated for HSSI interface and how to fix this problem ?
