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 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 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 Firewall :: Maximum Number Of 1-1 Static Nat Entries On ASA 5515X Or 5525X?

Aug 7, 2012

I have a FWSM cluster that I exceeded the maximum number of static nat entries on.  i migrated the connectivity off to a pair of PIX 535's that seem to be handling the adderess translation needs.  however the number of NAT entries being required is increasing and being the PIX series wal EOL'd several years back..I need to replace them..  The static 1-1 nat entries cannot be summarized into network as the hosts that are being nat'd are scattered all over various micro subnets in the all 3 rfc1918 ipv4 address ranges and they are being manged directly by snmp and SNMP-trap and other services that prohibit the use of many-to-one nat.   Is there a mknown maximum number of static 1-1 nat entries that can be defined on the ASA 5515-x, 5525=x and higher ASA firewalls?  Say I wanted to be able to grow to 2500 or more static 1-1 nat entries.  I am currently running 2010 1-1 static host nats currently.

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 10.1.1.254/24
  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.

We've just invested in a pair of Sup2Ts to upgrade a Sup720 6509 chassis but I'm unsure exactly how the management port(s), aka the Connectivity Management Processor (CMP), should be configured (and patched) in a dual supervisor system?Is each CMP an independent entity or is the management interface configuration (IP address, gateway, etc) replicated between supervisors?If it's the latter then do both management ports need to be physically connected at the same time?

Cisco Switching/Routing :: Stale ARP Entries On 6500 Running IOS?

Sep 11, 2007

On occasion I will have to clear the ARP cache on a 6500 when a customer swapeeds out a firewall or firewall NIC.  The ARP cache will show the MAC of the previous device and will not update until either the ARP table refreshes dynamically (currenty at default time) or it is cleared manually.
 
Sometimes I need to clear it manually and sometimes is is refreshed dynamically when the new device comes up.  Inconsistant issue.... 
 
Under what circimstances will an ARP entry NOT be refreshed when a firewall or firewall NIC is swapped out.

Cisco Switching/Routing :: SUP720 - Unable To Boot From Disk0

May 26, 2012

Customer is using SUP720 with SP rommon image version 8.1(3), he is trying to boot the new ios image from disk0, but he gets invalid magic error. he fomat the disk0 but still he gets error when he boots from disk0. He suspect that it can't be flash problem but can be software of hardware as he has two flash with same issue on 2 switches.
 
Customer wanted to recreate, I tried in the lab, i was able to load from disk0, but sup in lab had 8.5(4).
 
Customer wanted me try with 8.1(3) version. But i was unable to downgrade the SP Rommon image. SP rommon is running in Gold region and I loaded the 8.1(3) from both disk0 and sup-bootdisk, even preferrence was given to region1 but still sup came up with gold region itself.

* Will i be able to downgrade from 8.5(4) to 8.1(3), if so, what are the steps.

* is there any limitation or bug where  8.1(3) will be unable to read disk0.
