Cisco :: 2600 Terminal Server Can't Connect To 3750 / 3560 Switches
Jul 23, 2012
I have a 2611XM that I am using as a terminal server for my lab setup. Async is using octal cables. It works great with routers of all different models, but when I connect a switch of any model, it does not work. The connectivity LEDs don't even light (they do for the routers). The switches in question are 3750s and 3560s.
I have tried straight through from the octal cable to the console port of the switch, as well as a rollover with a converter, no luck. This does seem to be independent of configuration on the console port - even before the console port of the routers were properly configured, I at least had indication of physical connectivity.

I have a cisco 2600 router with 4A/S module, can it become the terminal server? If yes, which kind of octal cable should I choose to connect to other cisco routers console ports?

Is it possible to use Port Security mechanism between two switch (3750 or 3560) ports while trunk has been configured? If it's not possible, is there any other way to ensure that no other Switch can be connected other then the one switch which has been configured/placed by a network engineer?

We have a couple of Cisco switches and connected a (Windows 7) laptop to one of them and it gets its IP address from a DHCP server.I can now ping the IP from all of the switches, no problem, also not when I log on to the core switch in the same VLAN as both notebooks. But from my (Windows 7) laptop, which is in the same VLAN as the target laptop, I cannot ping it.
I checked, default gateway is good on both sides, as are DNS servers.
Target notebook ---- Catalyst 3560 V2 switch === Core Catalyst 3750 switch (stack) === Catalyst 3560G switch --- My notebook

I have more than 20 Cisco switches in my office which is basically a soap manufacturing factory. The switches include Cisco 2950, 2960, 3560, 3750 etc. We have routers also which include 2821, 2951 etc. We also have Cisco WLC 2125 and LAP 1262 series. Sometimes all these devices management comes very tough to us.
We need to log on to different devices for troubleshooting/network management which sometimes becomes very tough to us. So I wonder if there any Cisco applications or tools by which we can centrally manage all these devices.

I am runing 802.1x and MAB authentication of devices connected to a 3560 switch (in test). When I run 'terminal monitor' I am getting alot of authentication fail-msg. Is it possible to get the switch not to show them? I have to do some debugging on SNMP and DHCP to be able to figure out why I get these msg, but since the switch is blasting out so many auth-msg it is hard to see the debug messages. [code]

I've been fighting what seems to be an increased number of outqueue drops on our core stack and edge switches for the last 3 or 4 weeks.(The core consists of a stack of 5 3750s in 32-gig stack mode. The wkgrp switches are 3560s. all are at 12.2.52) The wkgrp switches are directly connected to users. We use Nortel IP phones with the phone inline with the user PC. auto-neg to 100/full. [code] However I have tried turning off QOS on a couple of workgroup switches (no mls qos, but left individual port configurations the same) but am still seeing drops.Since I have disabled qos on the switches in question (no mls qos) (not the core tho) I am presuming these commands have no affect on the switch operation and therefore cannot be related to the problem. With QOS turned off one would presume that it is general congestion - especially at the user edge where busy PC issues might contribute. So I wanted to see if I could see any instances of packets in the output queues building up.
I wrote some scripts and macros that essentially did a snapshot of 'show int' every 20 seconds or so, and looked for instances of 'Queue: x/' where x was greater than zero.What I found after several days of watching the core stack, and a few of the workgroup switches that are most often displaying the behavior, was that I NEVER saw ANY packets in output queues. I often saw packets in Input queues for VLAN1, once in a great while I would see packets on input queues for fa or Gi interfaces, but NEVER on output queues. [ code] Additionally, when I look (via snmp) at interface utilization on interfaces showing queue drops (both core and wkgroup), they are occurring at ridiculously low utilization levels (as low as 4 to 8%). I've tried to look for microbursts between the core and a wkgroup switch where the core interface was experiencing drops, but haven't seen any (using observer suite). [code] While the queue-drop counts aren't critically high at this point, they are happening more frequently than in the past and I would like to understand what is going on... In most cases, no error counters are incrementing for these interfaces. Is there some mechanism besides congestion that could cause output queue drops?

I have 100+ 3750's that are running various IOS, some stacked and some not, and all seem to have the same problem.If I attempt to paste a configuration into the terminal session I get booted after about 10 to 15 lines. This happens when using SSH and Telnet. Telnet will go a little further before I'm booted. After I'm booted it sometimes takes a minute before I can log back into the switch. Any issues pasting configs into a 3750 via a VTY session?

What command sequence disconnects you from a TS session? My setup is as followsr1 > TS > 2009-2621XM 2010-3825-R1 2011-3825-R2I can connect from the TS to any of the devices. The issue is that I am telnet'd to r1 and from there telnet'd to the TS. So when I type "Crtl+Shft+6, x" I go directly back to r1 and not the TS. Furthermore if I resume the session on r1 the TS is still connected to whatever session I was in prior to disconnecting. I've experimented with the disconnect and escape characters but I'm at a loss what it is that changes this.

We have the 16-port (NM-16A) and 32-port (NM-32A) asynchronous (async) network modules which provides 16 or 32 EIA/TIA-232 (formerly know as RS-232) data terminal equipment (DTE) serial interfaces at speeds up to 134.4 kbps . Few of the interfaces are connected to the console of cisco switches and routers , now we need to know that the remaining interfaces can be connected to console ports of devices other then cisco Systems to manage them , Will it work with them ?

I am running ASA 5505 release 8.2(4) using a clientless SSL vpn to connect my assessors to the server via RDP to a Terminal server. Everything was working fine until last week when we had a Internet outage. During the outage some of the assessors claimed to have accepted a Cisco add-on to get into the site. once the internet came backup they could not connect to the terminal servers - what would happen is they would click on the link - say OK to connect the clipboard and the screen would pause for a few seconds then right back to the select options page.
they can get to other servers (non-terminal servers) but not to the ones they need. I can recreate the issue by waiting a REALLY long time before replying to a prompt to install an cisco add-on. I have users that can connect and others than can not. Also this only seems to affect Internet Explorer 8 and 9 does not affect Firefox

Plese find attached the config file. I could not find proper docs on setting up this device as a terminal server. I have followed the following link but did not work.
[URL]
There are 16 Async (0/0/0 - 15) interfaces and also the following lines.
line 2line 0/0/0 0/0/1line 0/0/2 0/0/15
How can I connect to other Cisco devices via the terminal router?
usage of above 16 Async interfaces and lines.

I've heard that you can configure an 1811 router as a terminal server for remote console work.I have several of them in the lab and would love to try it out.

I have rolled out Terminal Services on Server 2008 R2 for a company I used to work for, it worked perfect the users could go home and browse to our web domain and login and use apps straight from the server.there'd be no Microsoft stuff to be accessed just pure Linux Servers but probarbly if users access the online terminal services on Linux they'd be using a Windows PC

PC-1 connect to printer as local printer but shared for other PC.
PC-2 through TS can see the shared printer. This is OK. But when the printer move and connect to PC-3.
PC-3 connect to the server through TS and want to have print out some document from the server to the printer. But unfortunately the Printer cannot be seen through TS. Even the printer already shared.

But server has on time and the Switch another. I test this NTP with CUCM and is working fine, the issue is with ther server?

Using EMM as a nice friendly interface for their terminal server (ie router with NM-16A and octal cables)?when I ask the framework to run the following command it gets stuck will a blinking cursor and clear screen
<IOSExecCommand>"connect 10.1.1.1 2000"</IOSExecCommand>
however removing the port number allows it to connect fine.
<IOSExecCommand>"connect 10.1.1.1"</IOSExecCommand>
same symptom if iI were to replace connect with telnet
<IOSExecCommand>"telnet 10.1.1.1 2000"</IOSExecCommand>
even setting up an iphost does the same ie:
ip host R1 2000 10.1.1.1
<IOSExecCommand>"connect R1"</IOSExecCommand>
All of these commands work fine from the # prompt

I've a RV082 with 2 internet connections.The idea is to permit external connections to my server and if one Internet line falls, automatically switch to the other.
We have configured the router in Smart Link backup.We try to connect with WAN1 and WAN2 enabled and all works fine.
We try to connect with WAN1 disabled and automatically WAN2 is activated.The problem start here...if WAN1 is activated while there are connections using WAN2, these connections falls!
How I must configure the router to permit that active connections are not disconnected from WAN2 even when WAN1 connection come back?

I have a Cisco 2901 Terminal server with AAA authentication via ACS server. I create twoaccounts on the acs server, cciesec2011 and vendor. Both accounts can log into the Cisco 2901 Terminal Server without any issues. By the way, I am NOT using AAA authorization on the Cisco Terminal Server. Once cciesec2011 or vendor accounts are authenticated, theseaccounts can access all the async line on the Cisco Terminal Server.
Now I have a new requirements. I would like to allow cciesec2011, once this account is successfully authenticated, this account has access to ALL async line on the Terminal Server. The "vendor" account, I want to restrict this account access only to async line 35 (there are 32 async lines available on the Cisco Terminal Server) and nothing else.
How can I accomplish without using AAA authorization on the Cisco Terminal Server?Is it possible to use "privlege level" to accomplish this? if so, how?

Any example of router config for a terminal server.In fact I need a configuration for a router with multiple, low speed, asynchronous ports that are connected to other serial devices, for example,modems or console ports on routers or switches.With this router I would like to use a reverse telnet to connect with my devices using the serial connection.I find many examples on the Cisco web site but none with my router hardware configuration.My router is a 3620 router with a 8 port async (NM-8A/S) network module and I would like to use the 8 serial interfaces, each of them connecting a serial device.

I have verizon wireless router to connect to the internet via FIOS. The public IP on the wireless router is DHCP assigned. I have my home lab with cisco 2511 and octal cables. I would like to be able to access the terminal server remotely via the internet when I'm not in. I'm concerned cause the wireless router is DHCP assigned IP. Even if I have a static IP on the ethernet port of the 2511 connected to the wireless router, I'm not sure if the NAT will work so it can be accessible from the internet.

I have a switch(6500) with 2 vlans(2 SUBNETS) and from the other side of my network i have 2 terminal servers.
I want to have a VIP in my 6500 switch which i have the 2 vlans and when the first vlan(network) try to connect to the VIP
my switch will forward to first terminal.When the second vlan try to connect to VIP the switch will forward to second terminal.
I'd like the switch to decide in wich terminal server will forwared the packet based on source network.
I am not sure how i can do this???I use VIP with SLB???I use NAT???PBR?

I have an annoying problem with networked printers disconnecting/disappearing when TS users logoff. Current configuration is: SQL server (WinSvr 2K8 R2 Std) has printers installed on it (standard TCP/IP Port) and printer is shared, there are also some printers installed on the DNS server and a couple of satellite offices. Users connect to TS servers (WinSvr 2K8 R2 & WinSvr 2K3) printers are connected and work fine until they logoff, when they log on the printers are gone "sometimes some printers are still there!?" I have tried logging onto the server as domain administrator and connecting printers but they won't even stay for administrator (have had this with win7 client machines) and tried directly 'console' at the server. I have looked at the printers on the SQL server and sharing properties, it is stoping printers from coming back at login on TS Note that local (client machines) connecting to the same shared printer from the SQL server don�t have the problem it's just on the TS server.

I have a set-up with multiple C2960 and C3750 switches. All these devices are being managed remotely. So basically I login to C2901, which is used as a Terminal Server, and reverse SSH to the console of each device. That's - I have assigned an IP to each port of the terminal server so that I can SSH directly to the desired device through via the mapped IP.
Now, recently I had to restart couple of switches - one C2960 and C3750. I initiated the reboot via console connection remotely. I could see the device logs for some time and then the logs stopped and there was no reaction from the console irrespective of any command I tried to enter.
I tried resetting the line on the terminal server, but that didn't work.
Now when I try to SSH the IP mapped to console of that particular device - i dont get any login prompt and there is no effect on device after giving any command. Although i can see the logs on the console session - but cant do anything.
I have a second way of connecting the device via inband- management, and checked the device config found it correct. It is same as other devices which are working correctly.
Both C3750 and C2960 are behaving exactly same - can see logs on console but see effect of even pressing enter - not getting login prompt as well.

I have two 3750 layer3 switches and I need to connect them via stack cable.so if I connect them with the stack they will be act as an one switch, but for the configuration if I create a VLANs on the master switch (applied all the configuration on the master one) this configuration will be transfered to the slave one or I have to repeat the configuration that I did on the master.
