Greetings,
I have a 2851 and a 1841 both serving as hub routers in a GRE multipoint configuration. They are both receiving buffer misses and failures on startup. I will post the output of show buffers below:
LAB-HUB-RTR#show buffers
Buffer elements:
607 in free list (500 max allowed)
9071 hits, 0 misses, 618 created
Public buffer pools:
Small buffers, 104 bytes (total 71, permanent 50, peak 71 @ 00:11:33):
68 in free list (20 min, 150 max allowed)
7083 hits, 74 misses, 0 trims, 21 created
55 failures (0 no memory)
Middle buffers, 600 bytes (total 39, permanent 25, peak 39 @ 00:11:25):
37 in free list (10 min, 150 max allowed)
2233 hits, 42 misses, 0 trims, 14 created
32 failures (0 no memory)
Big buffers, 1536 bytes (total 50, permanent 50):
50 in free list (5 min, 150 max allowed)
118 hits, 0 misses, 0 trims, 0 created
0 failures (0 no memory)
VeryBig buffers, 4520 bytes (total 10, permanent 10):

0 hits, 0 misses, 0 trims, 0 created
0 failures (0 no memory)
Large buffers, 5024 bytes (total 0, permanent 0):
0 in free list (0 min, 10 max allowed)
0 hits, 0 misses, 0 trims, 0 created
0 failures (0 no memory)
Huge buffers, 18024 bytes (total 0, permanent 0):
0 in free list (0 min, 4 max allowed)
0 hits, 0 misses, 0 trims, 0 created
0 failures (0 no memory)
I have tried increasing the small/medium buffers initial size and permanent size, however there is no change. The buffer failures for small and medium buffers are always around this many every boot.
I have also changed the IOS versions between 12.4.24(T4) to 15.1 with no luck in stopping the failures.
Thank You for any information you can provide.
