Cisco Switching/Routing :: 1700 - Setup For Connecting Router AUX Port To Switch Console Port
Feb 26, 2012I was looking for a way to connect an AUX port from a 1700 router to a 6500 switch module console port, to see the output of the Switch's on the 1700 router, in case there is a network downtime, I could see what's going on in the switch, what cable should I use ? Also, is there is any kind of documentation for this type of config what have I seen is very few info.

Feb 13, 2013I 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.

Dec 11, 2011I 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, 2011I 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 Switching/Routing :: Need To Know RMA Procedure VS S720
Dec 3, 2011we purchase only Cisco Supervisor Engine VS-S720-10G and use it in our old C6509-E chassis.Now the supervisor engine was dead,(means not working and no LED's are ON). How can i claim the RMA from cisco?
We purchase from one of our partner. We send it to them,they are not able to find the Serial number from the Supervisor Engine module (Because lot of serial numbers are on the board). Also the customer through the catoon.
Now how we can know which is exact serial number of sup? How to get RMA from the Cisco on which serial number?
Cisco Switching/Routing :: VSS With VS-S720-10G-3C And WS-X6748-GE-TX Compatibility?
Feb 7, 2012We are upgrading two standalone 6509E chassis to a VSS system with new VS-S720-10G-3C cards. The 6509's have WS-X6748-GE-TX card with DFC3B daughter cards (see below). The compatablity matrix (see below) states that 67xx cards are supported but it goes on to state DFC3C or DFC3CXL cards are needed. So does this mean that the existing WS-X6748-GE-TX cards have to be upgraded or will they be supported?

Cisco Switching/Routing :: Is It Better Take 6724 With DFC3BXL Then Only S720-3BXL
Jan 22, 2013We have 7 interfaces with rj45 connections.. all around 100Mbit per connection .. most likely in the future we will need a couple more interfaces.. i was thinking it would be better to take a WS-X6516-GE-TX card then a FE card as for example a WS-X6148-RJ-45 .Now we want to implement a 7606 with a SUP720-3BXL with 1GB dram for the RP(MSFC3)... so enough memory to support the 2x a FULL BGP table to two peers.
Q : Does the SUP720-3BXL work well with two peers sending the FULL BGP table ?
Q : And does that also work with a WS-X6516-GE-TX connected to the two peers sending the FULL BGP table ? .. or is it better to take a 6724 linecard with a DFC3-BXL so that the 6724 will lookup routes locally instead a 6516 will have the S720- perform the routing ? I know that adding the DFC's increases the bandwidth of the chassis significantly (40gbps per slot most 6700 linecards ,and 20gbps for the 6724 which is 1:2 oversubscribed )
Q: Or is it better to connect the two peers to the two SFP interfaces on the SUP720 , and connect the small routers and customer networks to the 6516 linecard?

Networking :: Upgrading 3640 IOS Via Xmodem Console Using ROMmon
May 10, 2011So apparently the 3600 series do not support the tftpdnld to upgrade your ISO when you upgrade your flash. You have to use the Xmodem transfer as described here: Xmodem Console Download Procedure Using ROMmon [URL]. everything is going great but it is going to take another 3 hours.
Now when i installed the new flash at bootup it said the "device does not contain a valid magic number" now that is just because the flash is not formatting correctly and downloading the new flash file automatically formats the flash setup?
Cisco Switching/Routing :: Configure Egress Netflow In 6500 (VSS) With VS-S720-10G Supervisor?

Cisco Switching/Routing :: 6500 Sup VS-S720-10G Traffic Forwarding In Active And Hot State
Jan 24, 2012I have catalyst 6500s with two VS-S720-10Gs, one is in Active and one is in Hot state. Both Sup cards have two 10G uplink ports. How does the traffic forwarding works in this case on the uplink ports? Do these uplink ports actively forward traffic or it is only the uplinks ports on Active that forward traffic? I see CDP neighbors on both Active and Hot SUPs uplinks ports - it indicates that packets are flowing on both cards.
I want all uplink ports on both SUPs to actively forward traffic. Does it work? What is the config for this?

Apr 14, 2013we have multiple Video production networks, with Video servers (AVID Unity ISIS) connected by 10GE fiber links to 4948-10GE switches. On almost every of these switches, I see more or less "Sequence-Err" interface errors. We do not currently have a known problem because this, and no other errors are seen. But I would like to understand the error, and therefore I would like to find out, what a sequence error means, what the cause is, and what the impact (to a frame) is?
By the way, it is well-known that the ISIS Video server does generate very excessive UDP data bursts. Maybe this matters? On Cisco doc I did not find an answer. The document "Troubleshooting Switch Port and Interface Problems" does unfortunately not refer to "sequence-err".
Here is an example output:

Cisco Switching/Routing :: Cat 6506 Goes Into ROMmon
Nov 29, 2012I have a Cat6506. There were 2 Sup 720 in it for redundancy. They told me they had problems with this thing in the past needing to go out and reboot the machine. I need to go out periodically because it goes into ROMMON. I type boot and it comes back up. One time though neither one would reboot. I had to take a third one out there and reconfigure it. Now it is starting to do the same thing. One thing I did notice is they never connected it to an UPS. It is plugged strait into the wall with power going to two outlets. I am beginning to think there are spikes in the power occurring and this is sending it into ROMMON.

Cisco Switching/Routing :: Cannot Get Out Of Rommon Mode 1760
Dec 10, 2011I'm currently pursuing to take my CCNA and am currently studying for it, but have recently encountered a problem with one of my 1760 routers that I can not solve.Yesterday I went to boot up my router like normal, however when I went into hyperterminal I noticed the router was in Rommon mode. Thinking I could change the configuration registry, I tried to bypass the NVRAM by using confreg 0x2142. However this still causes the router to go into Rommon mode. I am getting an error that states that there is insufficient memory to load the IOS image. [code]
I have used the dir flash: command and can see the IOS image, and try to boot from it (boot flash:iosimagename) but it will still go back into rommon mode. I also just swapped the RAM from my other 1760 into this 1760 and it booted up and went into normal configuraiton mode without any issues. However, the other router now will not load it's IOS image and I get the exact same error.I'm at a loss here, and have searched to figure out where or how I can just wipe the router clean to try and start fresh, but cannot get out or Rommon mode. The only thing I can think of is that the RAM went bad since it wont boot up either machine.

Checking through the various documents on CCO I dont find any reference to rommon on this card, but do find information on using the CMP to support the supervisor. I logged into the CMP but couldn't find a way from there to do a password reccovery either.So, is the `normal' IOS rommon/password recovery method supported.
