Re: MSFC
Is it possible that you erase your flash too and the router is booting up from the mini IOS in ROM? Try to sho flash and see if it has an IOS. If not restore or copy from tftp.

Re: MSFC
The reason it's in router(boot) mode is because you've erased the "boot system flash bootflash:" command that's needed to find the boot image. Do a "show flash bootflash:" on the MSFC and check for the second image listed and copy the name down EXACTLY (not the boot image name). Enter config mode on the MSFC and enter the following: boot system bootflash:.image name from flash It should look something like this: boot system bootflash:c6msfc-js-mz.120-7.XE1.bin Do a write mem and then reload the MSFC. You should then be able to get your full IOS loaded. Timothy Mark Jones Network Engineer Cisco CCNA, CCNP, CCDA, CCDP Ficomp, Inc.

RE: MSFC
Jeff, Try this link: http://www.cisco.com/warp/public/473/14.html , it has the recovery procedures if you have erased the msfc's bootloader flash. It is not too bad if you have a 4500/4700 router to reinstall the image. Otherwise you can try the xmodem procedure (it did not work for me). I had to have TAC RMA a replacement flash. It's embarrassing but there is just not a good recovery procedure if you don't have a 4500/4700 handy.

Re: MSFC Routing
Daryn, you don't say which switch you can't ping from the server do you have a vlan interface (as opposed to a vlan) defined in the 2924 switch? by default the IOS will only create an interface for vlan 1, and will only let you have one interface live at one time - a bit like having the sc0 interface assigned to a particular vlan on the Cat5X00/6X00 series. I'm assuming that you can see the vlan on the 2924 - ie it is talking vtp to the 6500, and the vlans are being propogated (the vtp communities do match don't they?). do the encapsulations on the trunk match? try turning pruning off - keep the number of variables down until you get them talking initiailly Does the trunking work between the two 6500s? Can you ping back and forth between the two MSFCs? is HSRP working or are the two interfaces both in active mode because they're not talking to each other? hth Andy - Original Message - From: Bartlett, DS1 <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, June 29, 2000 11:30 PM Subject: MSFC Routing > I have two 6506's with MSFC PFC cards attached to the supervisors.

Re: MSFC [7:30668]
You have three choices. 1 Treat the two MSFC's as two individual routers 2 Config-sync, basically you configure the routers individually but from the active router 3 SRM, single router mode, you have a single router config, one active one standby. of coarse this is ASSuming your running hybrid mode In Native mode the box is just a big router and if you have two MSFCs one is active the other standby. see http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sw_6_3/confg_gd/redund.htm Dave "[EMAIL PROTECTED]" wrote: > > I have a 6509 switch with 2 MSFC's.

Depending on your topology. If you have only one Cat, I would definitely configure it as two separate routers.

As soon as you turn on single-router-mode, it will sync up the redundant MFSC on that switch automatically. Of course this will need to be performed on every switch that has redundant MFSC's installed. There are also a few things that have to be checked first i.e. both MSFC's are running Cisco IOS release 12.1(8a)E2 or later, stuff like that.

RE: MSFC [7:30668]
The choice of running your MSFCs depends on your COMPANY'S POLICIES. You will need to test the different standby settings for your MSFCs. With our tests, we noted that both standby techniques had some nesciences. We decided to stick with running with the MSFC's independent of each other. ADVANTAGES of separate MSFCs in one 6509 : Predictable workings of MSFCs, isolated. DISADVANTAGES of other Methods : Temporary rooting loops(while updates were sent from 1 MSFC to the other), loss of configuration, loss of config changes. Etc. Generally, we could not predict at which state the MSFCs would be at a particular point in time. We used EIGRP as the routing protocol of choice. It works well, with the 2 MSFCs in the 6509, providing redundancy between the 2 MSFCs Hope this helps, AKI -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Woods, Randall, SOBUS Sent: ?a?as?e??, 4 ?a???a 2002 5:12 55 To: [EMAIL PROTECTED] Subject: RE: MSFC [7:30668] As soon as you turn on single-router-mode, it will sync up the redundant MFSC on that switch automatically.

Re: MSFC IP helper-addressing [7:9736]
I would stay away from directed broadcasts for IP helper commands. Remember that ip helper not only forwards DHCP, but Netbios and NTP stuff too. You can turn the unneeded broadcast off with the "no ip forward protocol" commands. Try and just use unicasts on you helper commands and watch utilization. I know that there are a lot of bugs related to this command on MSFC's. A different version might be needed.

RE: MSFC CPU Utilization Pegged at 99%....but a sh proc cpu does not reveal anything past 1%
Actually traced the issue down to a device (possibly a 2948 Switch) sending a stream of UDP packets causing the CPU to peg. Filtered all UDP and everything calmed down. In the process of tracing down the culprit. Thanks for everyone's input.
