Cisco Switching/Routing :: 6509E - Installing And Setting Up Second Sup720

Feb 27, 2013

Trying to find documentation on the proper procedure for installing a second sup720 into our 6509-E chassis for sup redundancy. I have found documents that tout how 'cool' and 'awesome' NSF/SSO, and all that is, but haven't found any docs on installing a second sup720 into a chassis that is currently in production and is only running one sup720. In all the years that this chassis has been out, there must me a documented procedure out here to explain this.I have been through the following pages, and have found nothing to this effect.

Cisco Switching/Routing :: 6509E - Four Port 10G Blade Buffers 16M

Dec 29, 2011

Looking at the specs for WS-X6704-10GE, it shows the port buffers at 16M per port. This doesn't seem like very much for a 10G port. Is this upgradable or related to how much RAM is in the blade?

Cisco Switching/Routing :: 6509E Port-channel Flapping When Two More Links Are Added?

Sep 11, 2012

I have two Core 6509E SUP2T configued as VSS and has two 48 ports fiber blades. I have two 3750s, I have two gig on each 3750 port-channle to po1 and connected to both the core, one link to each core.Now, I was asked ot add two more links on each 3750 switch to make it a total of 4 gigs on each 3750s (all 4 gig ports/uplinks will be in used an dtwo links to core one an dtwo links to core 2).when i added two additional links on 3750s and bundled them to po1, I created another port channel on core and bundeled the additional two gigs on each core to accomodate for the two additional links (ports on core switches are not consequtives).
 
adding these two additional ports makes the 3750 switches flap between managemnet vlan and po1.now, i am not sure if I must have added the two additional links on the core to teh current port-channel or core!? I have created another port-channel on core to accomodate for this currently!?

Cisco Switching/Routing :: 2801 Router Console Port Not Working?

Feb 13, 2013

I  have issue with Cisco Router 2801's Console Port. My student was doing a  lab and he said during configuration, Console Port stopped responding.  He was in middle of configuration, so now at present, only telnet is  able to login on "R2>" user mode, enable password is not set, so  getting "R2>en % No password set R2>" I have tried  different terminal software but no output from Console Port, changed the  Console Cables, replace with working console cables, change speed  (baud) settings. Also tried to connect same console with "AUX" port and  got same error mentioned above. AUX Port responds but I am not able to  change mode (R2#) because of incomplete running-config. it seems "Console Port" is physically  damaged.

Cisco Switching/Routing :: 2924 Switch - No Response From Console Port?

Dec 11, 2011

I have 2 Catalyst 2924 switch in a home lab.  Both of them have developed the same problem at the same time (strange).  I have tried all that I can think of.  I can  telnet to them but cannot access via the console port.  On a telnet session I execueted a "write erase, reload" on one of them.  As I anticipated this threw me out of the telnet session and I presently have no access to that switch.
 
The console cable is fine, works for all other devices.

Cisco Switching/Routing :: 3560Gs / 4900Ms / Starting SSH Session From Console Port?

Dec 29, 2011

I console into switch 1 (or router, it doesn't matter) and everything is fine.  From that session I SSH to switch 2 (or router).  The session on the second device has a noticable delay when I type.Next I SSH to switch 1, then SSH to switch 2 from that session.  Everything works fine.Finally, I console to switch 1, and telnet to switch 2.  There is no delay.So it appears the delay only occurs when I open an SSH session while consoled into a device.  It didn't matter what switch 1 and switch 2 were - I had 3560Gs, 4900Ms and a 3845 router.  There's no special configuration on the console or vty ports - when I do a "show line console" and "show line vty 0" the output is basically the same.

Cisco Application :: 6509E - Standby ACE20-MOD-K9 Reboots On Its Own

Jul 15, 2012

I have 2 Cat 6509-E switches in VSS configuration with 2 ACE modules. One in each Cat6k. 
 
The ACE modules are running the following:
 
Software
loader:    Version 12.2[120]
 system:    Version A2(3.2a) [build 3.0(0)A2(3.2a)]
 
We have only 2 contexts, the Admin and another one that we redirect traffic to WAAS equipment. The ANM soft running is only used for stats about the ACEs. It is version 5.2.
 
Since last week, the standby ACE module reboots on it own. It rebooted between 10 and 15 times until we had to leave the module PwrDown due to the constant reboots.
 
I tried to find any bug in the soft but I could not find anything related to that.

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 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.

Is there a command to check what each input level of the power supply to try to identify possibly which source is causing the problem? The power supply input lights remains green while this is occuring.
