Cisco Switching/Routing :: 6509 Redundant Sup720 - Slave Boots Into ROMmon

Oct 24, 2012

I'm fairly new to networking and need to migrate an old core to a new core. I have a 6509-e Switch that I had an RMA on one of my 720 sup cards. After receiving the sup card I swapped my slave out with the new one, expecting it to boot into ios. It booted into Roman. I tried to boot the image manually and it did the same thing. I also tried to boot from my flash and, again, booted into ROMmon.
Question: If i configure and change the boot to boot from image it tells me i need to reset or power cycle first. Will this reset the entire switch? As this is production I'd rather not.
I am at home now, but I can supply any logs/hardware model/configs tomorrow. I thought I would see if this is an easy fix.

Cisco Switching/Routing :: 6509 / 720 Sups Random ROMmon Boots

Dec 27, 2012

Got a long lingering, year long issue that has spanned about 8 supervisor cards and a complete chassis swap. The 6509 acts as a ITN in our facility. The active sup card at random points of pipe usage boots into rommon mode, seriously inhibiting our company. I'm able to swap the 2 fiber pairs that we had going into the active supervisor card into the secondary and usually this works for another random amount of time, however, today it occured within minutes of hooking up the fiber links. Sitting there for about 5 minutes it booted into ROMMON. When this happens, I'm able to boot the sup card back to good status. Previous remedial actions, other than replacing sup cards/chassis, was checking the config register and making sure it was x2102. Previously, it was not, and we corrected and reloaded and it took, we thought this would fix the problem, until today.

Cisco Switching/Routing :: 6509 SUP720-3B / Dual Link With Failover And Redundant Configuration?

Feb 24, 2013

I have a two fiber connection from our Central Office(6513) to Remote office (6509). I have a requirement that on the remote office if one of the fiber goes down, the second fiber should work as a failover. I am planning to use SUP720-3B SFP to connect to the CO.

Can I connet one fiber to Sup720-3b G5/1 & another fiber connection to G5/2?  or Can I connet one fiber to Sup720-3b G5/1 & another fiber connection to G6/2? I am running EIGRP between sites. Any sample config.

Cisco Switching/Routing :: 6509 Goes In ROMmon On Reboot

Jul 24, 2011

I am facing a problem with a cisco 6509 that goes into rommon every time i restart. If i give the command
rommon 1> boot
it will pick up the IOS on the sup-bootdisk: or bootdisk: and boots up but i dont understand why on reboot it wont pick up this IOS and boot itself and why do i have to write boot command everytime on rommon.
I have also explicitly given the command "boot system bootdisk:IOSNAME.bin" in the startup config file but still no luck.

Cisco Switching/Routing :: 6509 - Upgrade Sup720 To Sup2T In VSS Cluster

Jun 21, 2012

I support an active VSS cluster using 2 x 6509E chassis with single Supervisor 3C modules in each chassis. I want to replace these with Supervisor 2T modules. All my service modules and line cards are supported with the Sup2Ts (I will also be implementing 6908 modules). Is there a document on the Cisco site for this? I haven't found one though I can find plenty that describe how to do a software upgrade.
(Note, I have a 3rd (non VSS) 6509E chassis that is also part of this core network and that will maintain VTP/V LAN's etc).

Cisco WAN :: 1841 Cold Always Boots To ROMmon?

Mar 4, 2012

we have 55 of the 1841 routers here, and one of them always boots to ROMMON from a very cold (down 1 hour or more) start.  The image on all 55 is c1841-ipbasek9-mz.124-24.T4.bin.  32 MB Cisco brand flash.  Here's what's been done thus far:In ROMMON changed to 0x2102.  Then 'reset' and the image boots fine.  Change config-reg to 0x2102.  Save config.  Reload and image boots fine again.  Wait an hour or more and boots to ROMMON.Boot from ROMMON to USBflash0:   Format the CF then copy over the bin file.  Change to 0x2102 and save. Reload and image boots fine again. Wait an hour or more and boots to ROMMON.Swapped CF with another unit.  Again, works fine to reload, but shut down and restart an hour or more later and boots to ROMMON.  Format this CF and copy over image while on router.  Image boots fine.  Wait an hour or more and boots to ROMMON.In each case of very cold start the configuration register has reverted to 0x0 {why it boots to ROMMON}Tried dx mode with 0x8001.  Nothing seen that is unusual to me, but I'm not an expert by any means.It doesn't seem to a CF card problem, but could be a connection to the CF card and then something behind that.
Here is the output of diagnostic boot mode:
Cisco 1841 (revision 7.0) with 116736K/14336K bytes of memory.
Processor board ID FTX1231W0JA
2 FastEthernet interfaces

Cisco Switching/Routing :: Setting Up VRF-lite On Redundant 6509-E To Account For Chassis Failure?

May 15, 2013

setting up VRF-lite on redundant 6509-E chassis to account for chassis failure?   Let's say I have 2x 6509-Es configured with HSRP for 2 vlans, ServerA and ServerB.  So
interface Vlan10
description ServerA VLAN
ip address
ip flow ingress
standby 1 ip
standby 1 priority 105

I now need to create an environment where the Server VLANs can be provided for two customers and they need to be wholly separate.   On 6509-A, I make VRF CustomerA  and VRF CustomerB  and I assign Vlan10 to VRF CustomerA and Vlan20 to CustomerB.   Do I create the SAME VRFs on 6509-B with the same logic?

Cisco Application :: 6509-E SUP720 And SLB Limitations?

Mar 21, 2012

We are looking into replacing our current Windows NLB configuration with a SLB solution as NLB creates some nasty multicast traffic.
We are currently curious about the limitations for running SLB without a dedicated ACE Module, will it handle line-rate speed (1 and 10 gbit) with SLB?
Does VSS introduce any limitations for SLB? Any other pitfalls/limitations we should be aware of?
Hardware info: 2x WS-C6509-E in VSS with VS-S720-10G (VS-F6K-PFC3C) running s72033-ipservicesk9_wan-mz.122-33.SXI7

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?

Cisco WAN :: Cat 6500 IOS Upgrade - Installing Secondary SUP720 In 6509-E

Nov 21, 2011

I will be installing a secondary SUP720 in a 6509-E and will be upgrading the IOS on the existing SUP which is on  122-18.SXF6. I've read that this release has passed End of Critical Maintenance earlier this you. I thinking of upgrading the IOS to 12.2.33-SXJ1(ED) or 12.2.33-SXI8(ED) (possible more stable), but i'm not sure if i need any step upgrades from the current version. The SUP meets the required hardware specs and I will also be upgrading the ROMMON to 12.2(17r)SX7 first.
I have alot of experience upgrading IOS on routers and switches, but i just need to now if there are any gotchas that i need to know for the upgrade on the SUP.
The other issue is i don't believe the current IOS has been installed, are there any issue running on an IOS not installed. Patching is not available since the system is not running from an installed image. To install please use the "install file" command.
