Traffic rate on ASA interface

[Harmeet Singh]

Hi,

I have ASA directly connected with Nexus switch. When i see the traffic rate at both side on directly connected interfaces, there is a major difference.

NEXUS-9K# sh interface eth1/41 | in rate
30 seconds input rate 270831600 bits/sec, 91518 packets/sec
30 seconds output rate 346781120 bits/sec, 108579 packets/sec
input rate 222.57 Mbps, 86.92 Kpps; output rate 294.91 Mbps, 104.57 Kpps

===========================================================

ASA/pri/act# sh traffic | be GigabitEthernet1/0
GigabitEthernet1/0:
received (in 121558.940 secs):
10204132362 packets 4832562247598 bytes

83023 pkts/sec 39479002 bytes/sec
1 minute input rate 1 pkts/sec, 599 bytes/sec
1 minute output rate 1 pkts/sec, 599 bytes/sec
1 minute drop rate, 0 pkts/sec
5 minute input rate 0 pkts/sec, 113 bytes/sec
5 minute output rate 0 pkts/sec, 112 bytes/sec
5 minute drop rate, 0 pkts/sec

Any reason behind it?

Is there traffic flowing over these links?  This looks like a bug behavior to me. Have you checked the release notes for the ASA version you are running?

Hi Marius,

Yes, Currently the connection count is 59523.

This ASA is in context mode and traffic is showing correct amount on interface when I am checking in context. But in system it not showing correct on that same interface.

To me this looks like a bug.  I have not been able to find any bug related to this yet though.  I would suggest opening a TAC case for this.  It could be a new bug.
