Hello!<br>
<br>
We have same issue with our 7750 with sfm2. We have large L2
segments (vpls on 7450s in aggregation) terminated on 7750 at L3
level. Our problem is caused by broadcast storms in access network.
This storms generate many mcast/bcast packets of protocols
configured on 7750 ip interface (example- arp, vrrp). Then 7750
tries to process this packets with its cpu. We can see this problem
interfaces with command "show system security cpu-protection
violators".<br>

<pre wrap="">Dear all,
I found high CPU IP Stack utilization on our 7750 SR7 (TiMOS-C-6.0.R4).
Router's main utilization is for Triple-Play service router.
Anyone found similar case ?
Thanks in advance.
