Cisco WAN :: 7613 - Redundancy With WS-SUP720-3BXL Module

Mar 20, 2012

We have Router CISCO7613,SSO redundancy configured with two Sup 720-3BXL running 12.2(33)SRC1 image. Even thought I've configured SSO, my standby sup remains in COLD state with the following logs generated.
Mar 20 22:07:32.514 IST: %ISSU-SP-3-PEER_IMAGE_INCOMPATIBLE: Peer image (c7600s72033_sp-ADVENTERPRISEK9-M), version (12.2(33)SRC1) on peer uid (8) is incompatible
Mar 20 22:07:32.514 IST: %ISSU-SP-3-PEER_IMAGE_INCOMPATIBLE: Peer image (c7600s72033_sp-ADVENTERPRISEK9-M), version (12.2(33)SRC1) on peer uid (8) is incompatible
Mar 20 22:08:48.263 IST: %PFREDUN-SP-4-INCOMPATIBLE: Defaulting to RPR mode (Runtime incompatible)

These logs says that due to some reasons, the configuration is not being synchronized with active and standby sups and hence the redundancy mode remains in RPR mode and SSO not achieved, and hence COLD state. However, I couldn't find a reason why the configuration is not being synchronized, I've issued the command, redundancy config-sync ignore mismatched-commands, and everything worked fine, SSO achieved and standby sup came to HOT state.Now my query is, 

1. Why the configuration was not synchronized and standby SUP got in COLD state??
2. Since I issued the suggested command, at least, some of the mismatched lines in configuration will be ignored, Will that create a problem when my Active sup fails and standby become active?

Cisco WAN :: WS-SUP720-3BXL And WS-X6748-GE-TX Configuration

Feb 20, 2013

I have the above config in a 6509-E chassis with X2 Cac-3000 psu's
The problem i'm having is when everything is powered up it runs fine for about 10minutes then reloads the switch,The 6748 has a 6700-CFC installed the only way i have managed to get it run without crashes is to remove the 3BXL card from the sup and replace it with a PFC-3B, whilst this has solved the problem the client wants the 3BXL card to be installed, am I right in thinking that the CFC installed on the 6748 is incompatible with the 3BXL or maybe the 3BXL is faulty

Cisco WAN :: 6500 Series Router Support Supervisor Module Redundancy Like 7304 Does

Jan 24, 2013

1) Does the 6500 series router support supervisor module redundancy like the 7304 does? IE, can I put two identical sup720 modules in the chassis for failover?

2) Can I use any ethernet interface on any line card on the 6500 series for router interfaces? If not, which line cards work as router interfaces?

3) Differences between the 6500 series and the 7600 series? Can I use a sup720 modules from a 6500 in a 7600?

Cisco Switching/Routing :: Is It Better Take 6724 With DFC3BXL Then Only S720-3BXL

Jan 22, 2013

We have 7 interfaces with rj45 connections.. all around 100Mbit per connection .. most likely in the future we will need a couple more interfaces.. i was thinking it would be better to take a WS-X6516-GE-TX card then a FE card as for example a WS-X6148-RJ-45 .Now we want to implement a 7606 with a SUP720-3BXL with 1GB dram for the RP(MSFC3)...  so enough memory to support the 2x a FULL BGP table to two peers.
Q :  Does the SUP720-3BXL work well with two peers sending the FULL BGP table ?
Q : And does that also work with a WS-X6516-GE-TX connected to the two peers sending the FULL BGP table ?  .. or is it better to take a 6724 linecard with a DFC3-BXL so that the 6724 will lookup routes locally instead a 6516 will have the S720- perform the routing ? I know that adding the DFC's increases the bandwidth of the chassis significantly (40gbps per slot most 6700 linecards ,and  20gbps for the 6724 which is 1:2 oversubscribed )
Q: Or is it better to connect the two peers to the two SFP interfaces on the SUP720  , and connect the small routers and customer networks to the 6516 linecard?

Cisco WAN :: Policing On 7613 SVI?

Aug 4, 2011

We have built some policers to apply to vlan SVIs on our 7613 so that we can rate limit input and output traffic.  We followed the Cisco formula and got this.
policy-map vlan-shape-3meg
  class class-default
   police cir 3000000 bc 562500 be 1125000    conform-action transmit     exceed-action drop     violate-action drop
There have been some complaints about this not actually meeting the limit.  When I do a show policy-map interface xxx I get this.  Based on that it looks like the Be value is being change to match the Bc value. 
On a separate note, I noticed that every policer we built with the cisco formula actually ends up with a Tc greater than the max Tc of .125 seconds. It seems odd that a recommended formula would end up creating values outside the maximum allowed limits by the software.
I'm not a QoS expert so if any of this seems like basic stuff it's just because I'm a little slow on QoS.   
   Service-policy input: temp-remove
   class-map: class-default (match-any)
Match: any
police :

One other order to apply policers input and output on an SVI does mls qos vlan-based have to be configured on the trunks tagged with the corresponding Vlan?

Cisco :: 7613 Having Frequent High CPU Utilization?

Apr 25, 2012

I have Cisco 7613 on my edge(MPLS Backbone). CPU utilization is shooting to 100% at frequent intervals. When I tell vendors managing device they tell that it is happening due to one of my server(connected on Fast ethernet port of 100Mbps) generating heavy traffic. My questions are:

1. Can a router of 720Gbps capability be choked due to traffic generated by 100Mbps link?

2. Interrupt CPU process utilization is well below 10% at the said time. BGP router process consumes most of the CPU. Does this means that server in question is generating too many routing updates?

3. Is there any way that I can limit routing updates on a particular link?

4. how to check which link is causing more CPU utilization.

Cisco Firewall :: Moving IDSM-2 And FWSM From 7613 To 6513?

Feb 5, 2013

I need your opinion regarding moving of IDSM -2 and FWSM Module from 7613 to 6513 chassis.Currently these two modules are in 7613 and we are not using either of them now we have to configure them in 6513 chassis. As you can see from the figure that traffic of all 3 core router i.e 7613 go to 6513 - to proxy ISA 2004 - 6513 - to Internet.
There are also some network attached with 6513 and we want to move both of modules to 6513 so that NetworkA/B/C/D/E which are attached to 6513 can also be configured for FWSM and IDSM -2.
I have a query regarding this migration:Do we need license for these two modules again for 6513 chassis?

Cisco WAN :: 7613 How To Adjust Change Over Buffer Size At Link-set Sub-command

Apr 13, 2011

I was wondering about command of Linkset subcommand at ITP7613.I have been using the Cisco7613 chassis for the ITP(SIGTRAN) service.
However, i know that the "tx-queue-depth" command is used for sctp multihoming buffersize that between primary and secondary path at the Link sub-command mode. but i can't adjust the changeover buffersize(retrieval buffer) that between link and another link at the Linkset subcommand mode.
It's above my comprehension.
My guess is that related to "plan-capacity-rcvd" command. it's right?I want to know command that adjust the buffersize of Link changeover.

Cisco WAN :: 7600 - QoS On Sup720?

Oct 16, 2012

I have a strange QoS problem with one Cisco7600 (sup7203BXL, IOS 12.2(33)SRE6).
This is layer 2 traffic,and all ports are L2 dot1q trunks:
1) Packet comes with DSCP 46 on Gigabit port (WS6728-SFP) with "mls qos trust dscp" configured. It goes out the port of the same card/slot with DSCP 0.
2) packet comes with DSCP 46 on different Gigabit port on the same card/slot with "mls qos trust dscp" and also "mls qos vlan-based" configured. It qoes out out the port with DSCP 46.
Why the switch behave differently if "mls qos vlan-based" is configured on port (or to say it works correct since it doesn't override DSCP)?
I have global command "mls qos rewrite ip dscp" since this 7600 is also MPLS PE router and I found in documentation that "mls qos rewite ip dscp" is mandatory for QoS on MPLS (EXP bits). So I can't turn off "rewrite ip dscp". Again the problem that I presents is L2 problem not MPLS (MPLS is used for different traffic).
Also mls qos mappings are ok COS to DSCp are 5 to 46 and vice versa.
Furthermore, as far as I know if I have configured "mls qos trust dscp" on Gigabit ethernet port, switch (7600) should work in this order:

- make internal DSCP from packet DSCP

- since I don't have configured DSCP mutation DSCP should stay the same (46)

- using map DSCP - COS ( 46 -5 ) switch will choose queue on outgoing interface in regards to mapped COS

Cisco WAN :: Migrating Sup720 Configuration To Sup2T?

migration of an existing Sup720 configuration to a new Sup2T. At present we have a Sup2T chassis in the lab running 15.0(1)SY1 and a production Sup720 chassis running 12.2(33)SXI5.I've taken a copy of the production startup-config, renamed it to 'startup-config-BGFL_6509_MBAS-020712' and copied it to the bootdisk (and slave bootdisk) of the new Sup2Ts.I've then added the command 'boot config bootdisk:startup-config-BGFL_6509_MBAS-020712' in an attempt to boot from that config and have the Sup2T migrate it to the new config standards (particularly from a QoS perspective as mentioned here :[URL]

Cisco WAN :: BGP Flapping After Upgrading 7600-SUP720 To 12.2(33)-SRD8?

Jan 23, 2013

We have a Cisco 7600 Router with SUP720/MFSC3 that was running version 12.3(33)-SRC3 for more than 2 years now. We recently had to upgrade to a newer release to solve a bug issue after recommendations, so we chose to go to SRD8 release. Since then we are facing a rather strange problem with one of my peer ebpg. we have 2-3 peering on the same router. only one of them is affected. The ebp keeps flapping every 3 minutes due to hold down timers.
12:14:33: %BGP-5-ADJCHANGE: neighbor Down BGP Notification sent
12:14:33: %BGP-3-NOTIFICATION: sent to neighbor 4/0 (hold time expired) 0 bytes
12:14:33: %BGP_SESSION-5-ADJCHANGE: neighbor IPv4 Unicast topology base removed from session  BGP Notification sent
12:14:47: %BGP-5-ADJCHANGE: neighbor Up

We asked our peer if they have similar problems but it seems they do not. Our peer is using Cisco 12810 running  12.0(32)SY11 After downgrading back to version 12.2(33)SRC3 again, the probem was fixed...

Cisco WAN :: Sup720-10G 6509 - Multicasting In Same Vlan Broken

Oct 9, 2011

Currently we do not have multicat routing enabled on either of our 2x Sup720-10G 6509 Switches.  We have no intention of doing so either.  I am looking for clarification on how mutlicasting operates within a Vlan. 
IOS: s72033-ipservicesk9_wan-mz.122-33.SXH2a.bin
Our Vlan has IGMP snooping enabled.  Here is the output.
6509Switch#sh ip igmp inter vlan 25
Vlan25 is up, line protocol is up
  Internet address is
  IGMP is disabled on interface
we do not want to disable IGMP due to this one concern that I can't find documented. If we disable IGMP snooping on the vlan, what happens to multicast packets with a TTL > 1.  Do they get flooded to the entire switch and all Vlans?  Or does it stay within the Vlan?
