Cisco Switching/Routing :: Upgrading IOS On 6500 With Redundant Sup 720s
May 8, 2012
I sort of messed up and upgraded the IOS on one supervisor on a 6500 without doing the second, saved and reloaded. How to I get the 2nd one working again? When I issued a show module the "normal" Active sup shows active and the standby shows as Supervisor.
I have a doubt about upgrading Memory in Redundant Supervisor Modules Nexus 7K18, i read the Cisco Nexus 7000 Series Hardware Installation and Reference Guide, and the process for upgrading the memory in redundant supervisors do not says that i can have a lose of service, but it also says that both supervisor modules must have the same amount of memory for redundancy to work;If the switch has two supervisor modules, both must have the same amount of memory. If you upgrade the standby supervisor module to 8 GB of memory, you must then switch the active supervisor to standby and upgrade the new standby supervisor to 8 GB of memory.
I know that the 6500 with a Sup 720 reserves power for a redundant 720. If there is no plan to install that redundant Sup, is there a means of releasing that reserved power? I know that one approach would be to insert a card into that slot to cut the reserve down, but I need to reclaim all of that power.
I have a Cisco 6500 series switch with VS-C6509E-S720-10G ,I have two redundant supervisors between two chassis on the LAN with no add-on line cards ?
I need to know if I can use the redundant supervisor 10 Gb uplinks to form a layer-2 Port channel between the two 6500 switches as i do not want to use want to keep the port idle additionally I need more bandwidth between the two switches for my server farm?
I have 2 6504's running HSRP as my core. They are each etherchannel'd to my Datacenter switch (3750 Stack) -- see image below.The problem i a having is with the etherchannel status:
Core1 PO11 status w (waiting) Core2 PO11 status P(bundled)
DC11 PO48 status P -- but only to Core2 - the interfaces to Core1 are suspended. (See attached configuration documents) None of the devices have any information in the logs. I run this same configuration in my central location, but we are running Nexus 7000's. With the 6500's, do I need to split the port channels on the 3750 to allow them to negotiate the etherchannel? If I split the portchannels, are there any concerns? Should I expect to see the etherchannel status as P (Bundled) or H (Hot-Standby)?
We bought Cisco sup engine WS-SUP32-GE-3B for 6500 switches 2 nos for redundancy. I have connected 6 systems on each sup engine ports. How to clarify whether both sup engine will forward the data while one is Master and other is standby?
I am using 6500 with VPN Accelerator on this device. I have a dozen other VPN connections GRE and IPSEC to routers and ASA and other Juniper Firewalls.
They all work perfectly.The error I get is map_db_find_best did not find matching map (Never seen this error be for) [code]I can't put the whole config for security reasons.
How to replace a defective redundant sup. I read on several articles that inserting new redundant sup should not be an issue as the active sup will always send its configuation to the standby. We are running SSO on the Sup720. Should I switch it to RPR before I install the redundant sup? I read a case wherein they switched it to RPR from SSO before inserting the new redundant sup. My concern is the IOS mismatch since Cisco doesn't always send the same IOS on RMAs.What I am planning is this.
1. Save/Backup configuration 2. Remove the redundant sup on slot 8 (since it is a 6513) 3. Insert the new redundant sup on slot 8. 4. Check if all the configurations were synced from slot 7 to slot 8. 5. Copy the IOS from sup-bootflash to slavesup-bootflash. (if the IOS are not the same) 6. Check show bootvar to see if the boot variables are correct. 7. If bootvar is the same, reload slot 8 to boot the new IOS.
Is this a good plan or am I missing something? I am worried with this document if the redundant sup has a different software. If i insert the card in slot8, according to Cisco, it will revert to RPR. If slot 8 boots and it has a different OS, then slot 7 will switch to RPR even if it's active. Would I still be able to access the slavesup-bootflash of slot 8? Is it going to boot 100%? I read that doing a force switchover will cause a flip and RPR would cause the line cards to reinitialize and I don't want that. Well I am not going to do a force switchover since i want slot7 to be active and retain slot 8 as hot.
I would like to add a redundant supervisor to my core 6509. Is this tricky to do? I know they have to be running the same IOS. I am worried if I put the new supervisor in it will write over the exsisting running config.
Can 2 Cisco 4507E switches with redundant SUP6-E modules be connected togther using the the standard 10GB CX4 modules and CX4 copper cables? Are there any special modules or cables required.
we have 2 Supervisor IV modules in our 4507, i want to upgrade the IOS as its still on 12.2 and i am going to upgrade it to the latest.
my first question is, if i update the IOS on the bootflash will it replicate to the secondarybootflash?
secondly, can i force a reboot of the secondary supervisor, then the primary after the secondary is up? i'm just trying to minimise downtime and get a plan going.
is there a difference in 12 vs 15 that would impact my current config that i should be aware of?
let me know the exact meaning of attach ( yellow marked one)? the contractor was saying "it doesn't mean two switches as there is a built in redundancy in Cisco switch)"I don't think he is correct as I never heard about built in redundancy in Cisco Router/switchAny comment as this will affect the numbers from 55 (3750 v2) to 110....
We would like to add another Nexus5k to this topology. However, it has to be a zero downtime infrastructure add-on. When setting up the keep-alive, peer-link, vPC and vdc domain, will there be any upset in network traffic on the current N5k?Also, are the Nexus5k configurations synchronized or are they independent from one another? Before setting up the new 5k, should i configure it to teh 6509's, and vPC's to the Nexus2k's before setting up peer-link?
There is a Cisco Catalyst 6513 in my office. Recently we decided to setup redundant Supervisor Engine 720-3B. When we did it, its became STANDBY COLD, and then it reloads. IOS is equal on both supervisors. It must be STANDBY HOT (SSO) redundancy. There is a configuration and show ver and show module outputs, and log of my actions.
I was wondering if I am able to add a redundant power supply to an asr 1001 router that is in production without losing connectivity or causing any diruption to the Users - is it hotswappable?
below is the current config of link that is already up. I need to add another fiber redundant link between 6509 and 2960 stack. How to work on config Spanning side by not taking 6509 down after the change. 6509 is in distribution.
There are two Cisco 4900M L3 switches and two Cisco 2960 L2 switches. I need to configure the two L3 switches to operate as a redundant pair, as the servers connecting to them are connecting using bonded interfaces, which can only have one default gateway. So these two L3 switches need to have the same Vlan interface 1, 2 and 3 IP's set onto them.How are the two L3 switches made aware of each other? via a normal trunk? Is there some special configration for configuring a mated/redundant pair of switches? or are they both just configured as though they were the same switch, but linked?
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.
The SuperVisor engine in slot 1 of a Catalyst 6513 needed to be replaced because a hardware defect. The SuperVisor engine in slot 2 is active and running CatOS 8.5. The new SuperVisor engine for slot 1 came with CatOS 6.3 and was not syncronized auromatically after insertion. When the customer enter the command "Show boot" he get the output:
AG-A6513-51> (enable) sh boot BOOT variable = bootflash:cat6000-sup2k8.8-5-5.bin,1;bootflash:cat6000-sup2k8.7-6-2.bin,1;
I have a peculiar issue with a router whering I get the message in the Show Environment as below.

I know in the past on earlier models of the supervisors that you couldn't use all eight uplink ports(4 on each supervisor) simultaneously when you have two supervisors on the chassis. Is this the same case for the 10Gb uplinks on the supervisor 7-E on the 4500 chassis? I tried doing my research but couldn't find an answer.
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
6509-A# ! interface Vlan10 description ServerA VLAN ip address 10.10.10.2 255.255.255.0 ip flow ingress standby 1 ip 10.10.10.1 standby 1 priority 105
[code].....
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?
Does a portable RPS device either from Cisco or another manufacturer exists, that would allow you to move primary power for a switch without causing an outage? I realize that for the Catalyst 3560 for example, you can get an RPS 2300 or 675, but my understanding is that these are made for a more permanent installation, not to mention rather costly.
It looks like the RPS 675 is rather inexpensive after all, especially in the secondary market, but still rather large for toting around.
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.
The have around 80 staff and I think the current infrastructure is overkill for the size of the company. The current kit is old and they have no GB ethernet ports. They currently have:-
Core Switch: 1x Cisco c6509with a 48 port fast ethernet module (WS-X6248-RJ-45) and an 8 port fibre module (WS-X6408A-GBIC)
I'm looking to replace this with something with 72 ethernet ports and 8 fibre ports
Access Switches: 2x 3500Replacement needs at least 48 ports and 2 fibre modules each
and 2x 5500Replacement needs at least 72 ports and 2 fibre modules each.
I am in the process of upgrading our network switches and wondering if the .lic file will work with the new software or if I have to rehost for the move to 15.0. Its a remote site and I would like to get some solid info before I pull the trigger.
Also which IOS should I be upgrading to?
c3750e-ipbasek9-mz.150-2.SE.bin or c3750e-universalk9-mz.150-2.SE.bin
