I have found that the Catalyst 2955 series switches do not use an external MODE button for getting a switch into the switch: prompt, but they use a break sequence like routers do to get into Rommon state URL
So I was wondering if there is a similar mecanism that applies to other kind of Catalyst switches, like 2960, 3560 or 3750.
I'm on a Cisco 2955 switch and need to get ssh working which I have done on another 2955 (but don't have near me), what am I doing wrong?

I'm trying to allow 2 users to access as 2955 switch.
-admin privilege 15
-eousers privilege 2
When they both log in they just get to the user exec mode, how can I get them to go to their respective modes? [code]
I have installed Cisco 2955 Switch which already have x.x.x.x EA12 IOS and I copied x.x.x.x.EA13 into the flash: with intention to have EA13 enabled for IOS. I set the Global config for boot system by 'boot system (no falsh)x.x.EA13;x.x.EA12' but then also no luck and was showing EA12 in 'sh ver'. I then deleted the EA12 IOS and set the 'boot system flash:x.x.EA13'. I also had varified IOS EA13 by 'verify flash:IOS Filename', it verified the IOS.
But when I reloaded my switch, I'm unable to login and its in 'switch:' prompt (ROMmon mode - I believe). I then tried for flash_init, load_helper, dir flash: (showing me EA13 there) and finally boot flash:IOS Image file but no good news here... Output like this
Error loading "flash:IOS Image File EA13" Interrupt within 5 seconds to abort boot process. Error loading "flash:c2950-i6q4l2-mz.121-12c.EA1.bin"Interrupt within 5 seconds to abort boot process.
My guessing is that the IOS is corrupted (but its not showing me Error loading Image blabla...) I'm trying with EA14 of 4MB and I have 3 MB free spare and decided to remove EA13 first then through XModem try to upload EA14.
Any useful way and recommend me deleting EA13 and upgrading EA14... Also option to set boot image with having two IOS at the same time for permanent use.

View 1 Replies View RelatedAny way for password recovery on 3560X without pressing "mode button"? A way, for example, to reach ROMMON with some escape sequence as in routers?
I have SWITCHES with CISCO 3560X boards embedded and they don't have the "mode button" taken out. So, it's a problem if there's no other way of restoring it.
I'm been telnetting onto a 2955 and then upgraded the IOS and enabled ssh version 2 and then issues a "write", when I came back the exec-timeout had been issued and I was logged out of the router and now it is asking for a username and password and not just a password liek it did before enabling ssh. I havent yet put a username and password on yet, just the telnet.What would the username be if I havent set one?

I come across to use the Catalyst Switch 2955 and it has two Relay Connector with one Major (MAJ) and one Minor (MIN) as below picture.There is command line to trigger these two Relay Connectors. As below command to set the Relay Connector to minor for monitoring the power supply: alarm facility power-supply relay minor
1. My questions are when there is power-supply faulty, the Minor Relay Connctor (right picture) will be short-circuited, right?
2. If we connector the two ports (ports 4 & 5 at the left picture) with a normal cable to drive an Alram Bell (in short-circuiled or closed loop situation), do we need an external power supply to the Alram Bell? Or there will be power supply from Catalyst 2955 to the Alram Bell as well?

One of my clients is using Cisco catalyst 2955 industrial switch.I am doing the configuration for them and come across one setting of FCS Error Hysterasis Threshold. I know FCS is Frame Check Sequence.
I do not understand is what is the meaning the setting of Hysteresis in term of percentage stand for what purpose?For example, the default is 10 percent. If I set the value to be lower 5% and what is the impact on that? Is this more stringent than default of 10% or less stringent than default of 10%?
Need your expert input in sorting out the below problem.I have a cisco 6513 switch which is going into SP mode after a reboot whci i have done during BCP activity in my organization.Below are the log for your reference.
Code...
We have two 6500 core switches and one(primary) of them is running in VTP transparesnt mode and the other (secondary) one is running in VTP client mode. I would like to change the VTP mode of the second switch to transparent mode. Would it cause any issue. I guess i have to create VLANs onto the switch.
View 7 Replies View RelatedThe following discussion is based on cisco cat 6500 switches with two power supplies: p1 and p2. . Both power supplies are running in combined mode .Each power supplies is rated with 500 watts max( I just picked 500 watts for simplicity)Combined mode In combined mode, each power supply provides approximately 83% of its capacity to the chassis. This allows for greater utilization of the power supplies and potentially increased PoE densities
1) Let say our specific 6500 switch's configuration requires 1000 watts. We have two power supplies p1 and p2 ,each with rated power of 500 watts. Both power supplies must operate in combined mode. Will power supplies be able to meet the total load power requirement of 1000 watts?
Here is my understanding :The maximum power delivered by each power supplies is 83 percent of its rated power, assuming power supplies are running in combined mode.
So Maximum power delivered by power supplies
= 83% of p1+ 83% of p2
= 83% of 500 + 83% of 500
= 415 +415
=830 watts
Thus the required load of 1000 watts can not be met by our power supplies in combined mode.
2 )Suppose our switch's switch configuration needs 500 watts. Again our power supplies each rated with 500 watts, are configured for combined mode. How much power is being delivered by each power supply? Is it 83 percent of the total load i.e 500 watts?

View 1 Replies View RelatedI have a 3550 switch that was replaced at a remote site with no IOS. This is a switch not a router so tftpdnld does not work.
[Code]...
The problem is the switches interface never comes up so try to connect to the tftp server. I read on google it can't be done on a switch to copy from tftp to flash in rommon mode on a switch and to use XMODEM. My problem is I do not have access to it, I ssh into a 3640 which is an access server for all devices and that is how I have console to it, how to use XMODEM over ssh.
But I'm fairly certain that there has to be a way to just copy it from tftp? I have a 3550 local and when I put it in rommon mode it stops the port check at port, port 1 goes from green when you plug it in to off then port 2 changes to amber and the rest green. So just by the look of this I would believe tftp would work; you just need to use port 1.
I'm trying to get an IP_ADDR set on the management port in SWITCH: mode but for some reason the port seems disabled. PC shows connection unplugged. MGMT_INIT is not a valid command (not listed under '?' ). Bootloader version is 12.2(53R)SE2 FC1.

Recieved this unit from an individual who has very little knowledge (like myself) with the 800 series.
I'm having issues just getting into this device, when I power it on and console into the unit i am presented with an "Access Verification" prompt that requires credentials that I do not have/know.
At some point (not sure how) I managed to get to a "yourname#" prompt at which point I configured using this document here and created a username and password and some other basic settings, I saved the config and did a reload and it takes me right back to that "Access Verification" prompt.
Sould I be using the CCPE to gain access to this device instead? Is there a way to recover that "Access Verification" username and pass? How did I ever get to that "yourname#" prompt?
I recently configured a cisco 3750 switch for a stand alone network here at work, and on all our other switches and routers we use ACS to access everything. This switch being a stand alone I dont have that option.

How do you reset a 1252ag access point that has the mode button disabled?
View 2 Replies View RelatedI received the following info from Cisco's TAC and wanted to inquire further before I start reconfiguring the switch:
In a redundant Sup-6E setup, the following configuration is supported :
- 1 TenGig uplink on Active Sup and 1 TenGig uplink on Standby Sup
- 1 TenGig uplink on Active Sup and 2 Gig uplinks on Standby Sup
- 2 Gig uplinks on Active Sup and 1 TenGig uplink on Standby Sup
- 2 Gig uplink on Active Sup and 2 Gig uplinks on Standby Sup
If you invoke shared backplane mode, the following configuration can also be supported:
- 2 TenGig uplinks(blocking) on Active Sup and 2 TenGig uplinks on Standby Sup
- 2 TenGig uplink(blocking) on Active Sup and 4 Gig uplinks on Standby Sup
- 4 Gig uplinks on Active Sup and 2 TenGig uplinks(blocking) on Standby Sup
- 4 Gig uplink on Active Sup and 4 Gig uplinks on Standby Sup
Here's the command and information about the "shared-backplane" mode :- [URL]
Currently, we have 2 SUP 6-Es(Module 5 - Active and Module 6 - Stand-by) setup in a redundent mode. I am planning on changing the redundent mode to the shared backplane mode so I can use 2 TenGig converters to uplink 2 access-switches. We purchased 2 TenGig converters and here is how I am planning on using them:
1- One will be used to uplink to two 3750 switches(stacked)
2- One will be used to uplink to a 2960 using a Gig SFP
My questions are:
1- Do I have to install the 2 TenGig converters(4-Gig Uplinks) in the same Module? Or can I use one one in module 5 and the second one in module 6?
2- Will changing the redundant mode to the shared backplane mode require rebooting the switch or disrupt the funtionality of the other linecards?
