Hey I have recently deployed several 7201s (NPE-G2 Processor/1G RAM) in a network, which once primarily consisted of Cisco 3570 Switches acting as routers, but due to the requirement of more advanced features such as traffic shaping, MPLS, VPNs etc. My company has decided to purchase this platform due to the appealing pricing etc.
I've had quiet a bit of exposure to this platform in my past roles, more as an LNS / VPN contentrator ... and it seemed to do the job fine. I've gone ahead and installed IOS (C7200P-ADVENTERPRISEK9-M), Version 15.2(4)S based on a recommendation and the fact that this is the IOS which was purchased with the hardware. The routers (which have been deployed and in production) are configured to take a physical Gigabit hand-off for a Layer 2 - 200Mbps WAN p2p circuit and route the traffic to/from a stack of 3750X switches which is acting as a core. The design is very basic at the moment. I have no ACLS, Policy routing or anything out of the ordinary. I have simple ospf point-to-point adjacencies over the wan link and to the core switch (via a static port-channel) The issue: The routers are doing about 120Mbps/60Mbps on the WAN link and the reciprocal of that via the port-channel sub-interface towards the core stack. I see the CPU utilization is already at 35-38% constantly. Which I believe is very high considering the amount of traffic the box is supposedly capable of doing. The traffic is primarily voice traffic + web traffic. Naturally the PPS is higher than usual but well below the 2Million the box can do. PPS on WAN LINK = 45000 / 40000 PPS on Port-Channel = 40000 / 45000 Here is a sample of the "show proc cpu sorted" command: CPU utilization for five seconds: 33%/33%; one minute: 33%; five minutes: 33% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 1 0 4 0 0.00% 0.00% 0.00% 0 Chunk Manager 2 132 241474 0 0.00% 0.01% 0.00% 0 Load Meter 3 3220 89788 35 0.00% 0.00% 0.00% 0 LDP Main 4 0 1 0 0.00% 0.00% 0.00% 0 RO Notify Timers 5 749848 168032 4462 0.00% 0.05% 0.05% 0 Check heaps 6 1440 20371 70 0.00% 0.00% 0.00% 0 Pool Manager 7 0 1 0 0.00% 0.00% 0.00% 0 DiscardQ Backgro 8 0 2 0 0.00% 0.00% 0.00% 0 Timers 9 8 499 16 0.00% 0.00% 0.00% 0 WATCH_AFS 10 3824 26245 145 0.00% 0.00% 0.00% 0 ARP Input 11 8 1259247 0 0.00% 0.00% 0.00% 0 ARP Background 12 0 2 0 0.00% 0.00% 0.00% 0 ATM Idle Timer 13 0 1 0 0.00% 0.00% 0.00% 0 ATM ASYNC PROC 14 0 1 0 0.00% 0.00% 0.00% 0 AAA_SERVER_DEADT 15 0 1 0 0.00% 0.00% 0.00% 0 Policy Manager 16 0 2 0 0.00% 0.00% 0.00% 0 DDR Timers 17 0 5 0 0.00% 0.00% 0.00% 0 Entity MIB API Ultimately I want to know am I simply hitting a practical limit of the box already? I'm very scared to enable more WAN links on these routers as I am affraid it will max out the available resources. I am happy to provide any further information that is not provided in this message. The running config is extremely lean at the moment. MPLS /LDP is enabled CEF is running. All data packets (asides from OSPF and ISIS packets) are handled by CEF. I understand this platform is not hardware forwarding like an ASR, or the like. However it seems to be a little too soon for us to be stressing a box like this one.
