Cisco Switching/Routing :: Upgrade Catalyst 6509E CatOS To IOS

Nov 7, 2012

I have to upgrade two Cisco Catalyst 6509E from Catos to IOS. I would want to know the requirements hardware or software for upgrading. Which are the recommended images I must download? From cat6000-sup32pfc3k9.8-4-5 to the latest stable version of IOS, is it recomended to pass to another previously version before?
I have viewed the following links,[URL]but, it doesn`t mention anything about that. The image below is the result of the "show version" command of one of our Cisco Catalyst.

Cisco Switching/Routing :: 10G Upgrade For 6509E

Dec 9, 2012

I have a couple of 6509-E combined in a VSS system. I need to upgrade them to support 8 (or 16 at max) 10G uplinks. I already used the two built-in VS-S720-10G fiber connectors for VSL links. Which Ethernet modules do you suggest to use? are there any related upgrades that I have to do?

Cisco Switching/Routing :: Catalyst 3750 Low On Memory

Jul 25, 2012

have 3 Catalyst 3750 in same stack, the IOS version is 12.2(53)SE2. Today we can not telnet/ssh to this switch, but ping is ok, and switch function is ok. I try to access the console port, it show "low on memory, try again later". After I reboot the master switch in the stack, the master switch change to another switch, then I can telnet/ssh to this switch. I check the Ciscoworks server syslog report, there are many MAC address flapping error message, and I beleive the MAC address flapping occured before several weeks. ( the G2/0/15 & G3/0/15 is connect to a VMware ESX server and the EtherChannel config mismatch with this Catalyst 3750 switch ) How to mention the root cause of the "low on memory" problem and what is the abnormal memory usage ( free memory percentage below ?% )?

Cisco Switching/Routing :: Memory Leak On Catalyst 2960 And 2960S - Similar To Bug CSCts52797

May 6, 2013

after upgrading about 35 Catalyst 2960 and Catalyst 2960S to IOS 15.0(2)SE2, we experience a memory leak on several switches. After some days / weeks the switches are not accessible via Console/Telnet/SSH/Web any more. Only SNMP seems to work properly.Attached users do not experience any decrease in service.
Trying to connect to the console, we get following error message:

"% Low on memory; try again later"
The only (temporary) solution is to reboot the switch. The behavior is similar to Bug CSCts52797.With regards to the Bug notes this bug should only affect Catalyst 2960 with 64MB of RAM and should already be solved with IOS 15.0(2)SE2.
We experience the erroneous behavior with

-WS-C2960-48TC-S      running IOS 15.0(2)SE2
-WS-C2960S-48LPS-L  running IOS 15.0(2)SE2

Cisco Switching/Routing :: 3560G Upgrade Required

Feb 20, 2013

I have a  WS-C3560G-24TS-S running  12.2(50)SE5 with IPBASE. I have been told that the functionality i seek (multicasting) is only available in the IPSERVICES version of the software. I was reading up on upgrading and saw that i needed to do a show license and get the UID and Serial number and get a license that is tied to my box. But the show license command doesnt work wtih my box. i then found something that said that the 3560's were special in that way. Im not sure how to get this box upgraded. I have a different 3560 running the IPSERVICES elsewhere in my organization. Can i take the IOS Version and  update my switch to that?

Cisco Switching/Routing :: 10Gb Ethernet Connectivity Upgrade Required Between 2 6509s

May 1, 2012

We currently have 2 6509s with redundant Sup720-3b's and PFC3B daughter cards which are connected together over dark fibre using the Gb fibre connectivity built into the supervisors.
The requirement is to upgrade this connection to 10Gb as inexpensively as possible.
Do I need to purchase new supervisors in order to do this properly or can I use a separate 10Gbe module (we have a spare slot), i.e. can I get away without using the connectivity built into the supervisors?
The other idea I had was putting a couple of 3750-X switches at each end to sit in front of the 6509s and provide the 10Gb connectivity between sites.  I could then use the existing Gb uplinks on the supervisors whilst also providing connectivity for some devices that currently connect to the 6509s but could just as well connect here.

Cisco Switching/Routing :: Catalyst 2960 IOS Upgrade

Apr 9, 2012

I need to upgrade a Catalyst IOS, but I got a bit confused. The catalyst is currently running "c2960-lanbase-mz.122-35.SE5.bin", but I want to upgrade to "c2960-lanbasek9-mz.122-35.SE5.bin", in order to enable ssh. [code] What are the appropriate steps in order to upgrade to "c2960-lanbasek9-mz. 122- 35. SE5.bin". I have downloaded the tar file (c2960-lanbasek9-tar.122-35.SE5.tar)
1) Do I have to delete the old directory  (drwx 192   Mar 1 1993 02:07:21 +02:00  c2960-lanbase-mz.122-35.SE5)?
2) Are these the correct steps to download and extract the IOS?
3) Where will the tar files be extracted? Will an new directory be made or do I have to make one manually?

Cisco Switching/Routing :: Rolling Stack Upgrade Of Catalyst 3750

Apr 1, 2013

I want to run rolling-stack upgrades on several stacks containing Catalyst 3750X-switches. I have done as follows: Configured the redundant uplinks as active and stand-by.Started to upgrade by using archive download-sw /rolling-stack-upgrade /overwrite /reload The upgrade starts as expected BUT switch number 2 in the stack is reloaded BEFORE switch 1 is finnished, the result is of course downtime for the stack. The documentation says something about the command "boot time", but what is this command doing? The default seems to be 7 minutes, it this parameter the time the upgrade-process waits before booting the next switch in the stack? I would expect that switch number 2 is reloaded when switch 1 is up again after reload, and not after an absolute number of minutes, is the rolling-stack-upgrade not working this way ?

Cisco Firewall :: Catalyst 6509E - Web Services Not Working

we have installed and implemented a FWSM on cisco catalyst 6509E and defined two virtual of contexts work as datacenter firewall. initially it is configured to allow all traffic to datacenter VLAN. (permit any any) on test, it worked fine, except for one problem: all web services had degradation in performance, all server-client (non web) services worked very fine. additionally all https servies worked well.
Users connect to the web server bypassing the proxy, web services are expected to act just like other ones.

Cisco Switching/Routing :: Migrating Cat 6503-E VSS To Cat 6509E VSS

I want to migrate a Cat 6503-E VSS to Cat 6509E VSS. We plan to use the same supervisor that we have on the Cat6503E, for minimizing the configuration change on the Doing this, the vss link will need to be changed, due to the fact that the supervisor slot will change with the Cat 6509, slot 5 instead of 1.

Question: is there a way to just change the vsl-link interface on a existing VSS ?

Cisco Firewall :: Catalyst 6509E / Migrating From FWSM To ASA Service Module (ASASM)?

I'm migrating from a failover pair of FWSM modules across to a failover pair of ASA Service Modules. In order to avoid a "big bang" switchover I intend to migrate subnets from one to the other over a protracted period.With that in mind, whether there is any restriction on having FWSM and ASASM modules in the same chassis? A trawl of the relevant documentation hasn't revealed anything.In this specific case it is Catalyst 6509E VSS chassis pairs with Sup-2T.

Cisco Switching/Routing :: 9216 Changing MTU Size

Sep 23, 2012

I have VLAN X with MTU 9216 on Switch-A. I also have VLAN Y with MTU 9216 on Switch-B. But not their SVIs are MTU 9216.They are not communicating to each other on packet size of above 1500. This is because SVI VLAN X and SVI VLAN Y connect to each other  through SVI VLAN Z (Point-to-point Layer-3 connection between two switches).  Although SVI VLAN X and SVI VLAN Y communicate through SVI VLAN Z, this inter-link port is a trunk port carrying other VLANs but VLAN Z is a native vlan for which SVI VLAN Z is defined.In order to make it work.
1. Do I need to change SVI VLAN X and SVI VLAN Y to 9216?
2. Change MTU for VLAN Z and SVI VLAN Z to 9216?
3. DO I need to change MTU sizes for other VLANs that are on TRUNK port?

Cisco Switching/Routing :: Isolating Two Different VLANs With Subnets On 6509E Sup 2T

Oct 1, 2012

I have a pair of Core VSS 6509E SUP 2T. Two different LANs, two diff. Subnets. larger LAN has been connected to the VSS pair usng normal SVI and Post-Channles (has lots of closets 3750 stacks) and no problem. Second LAN, two closets, stacked and connected to each other via Port channel and trunk + SVI interfaces. Now, I have SVI interfaces for both LANs on teh VSS pair and that is causing traffic from one LAN to jump over to the other VLAN and rightly so because the VSS pair see both subnets as directly connected subnets. I was wondring if I delete the SVI for the second LAN and only keep the L2 VLAN this will be resolved> The reason for the second LAN to connect to the VSs pair is only that It has to go through the VSS pair to get to the WAN router (both LANs will go out through this Same WAN router) but WAN router is not my concern at this time. I need to isolate these two LANs/subnets traffic so no one VLAM traffic jumps over the other.I have also thought about VRF but at this point I am not sure if teh 3750 stacks supports VRF and if it does how to implement VRF on the second and samller LAN to just allow it go through the VSS pair in order to get to the WAn router.
