Good bye old faithful Access Router 2511

i actually really hate tabbed terminal sessions. I like having 4 or 5 windows open at once on the same screen so I can see immediate results when I'm messing with something

You can do that with any program that offers tabs for telnet. SecureCRT does it if I tell it to open the folder which contains all my console sessions that connect to my 2511.

I agree, I went though a phase of trying teratem with tabs, but not being able to place windows side by side to see whats happening is ewwww. plus I find alt-tab to switch windows is quicker than tabs any way.

Putty CM (Connection manager) has a pretty good tabbed interface. Easy switching between tabs, CTRL-Left/Right arrow.
I use it extensively both at real work and lab studies.

haahha great response thanks guys. yeah I do think open windows would be cool idea to see the results..but for now just having say 5 routers and 3 cat switches bam to bam I can be at each one back and forth is a Godsend! with my new configs and types of connections I can make use of managed ports.

vs ctrl+shift,6, x which can get old...from my accessr router 2511..
and sometimes I cannot connect for some reason sometimes from my 2511 and have to reinitialize my reverse telnet configs with cut and past. then it works again..

I didnt know putty could do that will have to check it out...what is CM? version

You don't have to do that. I've got my lab set so if you telnet to port 2001 on the 2511 then it connects you to line 1. 2002 goes to line 2. 2016 goes to line 16 etc...

I dont understand, bud.say one of my routers is called R1760_1
I type that in command line and bam I am logged into my 1760.
Then in order for me to get out of that session, I have to do the key combo (ctrl+shift, 6, x) to exit that R1760_1 session? how do you end your sessions? I have never been taught anything else to end a session
using reverse telnet with my 2511? can you explain how you do that?
thanks

Nope, just telnet directly to the port

dayne@porthos:~$ telnet 192.168.55.3 2005
Trying 192.168.55.3...
Connected to 192.168.55.3.
Escape character is '^]'.

R1>
telnet> quit
Connection closed.
dayne@porthos:~$

Once you close the telnet session, it kills the connection, no need to telnet directly to the access server

forsaken

but once I kill the telnet session with exit or quit
don't i have to reestablish session with say the name of the session like in my case it is R1760_1. When I kill the session doesnt it kill it from my acces list? normally i get out of each telnet session with ctrl+shift, 6,x and then I just type the squence number in my show session command list and if say my R1760_1 is session 5 I just type in a 5. If i quit a telnet session I have to type in th entire R1760_1 session name to reestablish it and then it gives it a new sequence number...?

Each telnet connection is a specific connection to a routers console port. Once you connect you're straight into the console port of that router. You don't need to type anything extra. If you close that particular connection then you disconnect from that specific router. You don't need to ever telnet to the access server itself.

Your original method of doing the tabbed sessions was to connect to each router over its network interface which wouldn't work if you start altering the topology or make a mistake.

No need to ctrl-shift-6,x anything unless you're telnetting from inside IOS. If you set the access server up right, you can just telnet to the access servers IP with the proper port for the line and you telnet directly into the console port of the router on that line using your native telnet client. Access servers aren't capable of only reverse telnet, they handle regular telnet too

Why use tabbed telnet when you have 30" of desktop real estate

Eh, it all depends on what you can lay your hands on for the cheapest. There are good deals on 2511's

What's your IOS for your 2511? I noticed that you have line 1 16. For whatever reason, I only have line 0 4. I am using c2500-is-l.122-15.T17.bin.

Is this limitation dependent to IOS? I've read somewhere that it is. However, one guy with the same IOS as mine has line 1 16.

@tiersten

I'll let you know tomorrow. I won't have time to check it out right now or when I get home tonight.

I'd think it was more hardware dependant than anything else. I have 16 async ports, hence lines 1 to 16

Oooopsss. I knew there was something wrong. I am talking about line vty 0 15. LMAO! Noticed yours had line vty 0 4. Nevermind then. I just read somewhere that they're getting line vty 0 15 with their 2511.

Forsaken GA

I am going to try that tonight and tiersten

you are 100 percent right on if I want to change some things
will try to redo my access router this week. thanks for some ideas
I just love that telnet tabbed look; i can have all my systems all 16 open and just go back and forth teach one..love it....30" screen would be nice but I am not sure my eyes could handle telnet sessions all over the place ahahahh thanks guys will try my telneting into my 25111..never knew I could do that....make sense though....

ah crap I can only telnet into my 2511 5 times vty 0 4 is only 5 telnet sessions what if i want 16 simultaneous telnet connections how can i do that?

configure vty 0 through 15.

Check one of your switches, since they usually default to 16 vtys.

You'll probably see the config for the default line vty 0 4 and then the config for line vty 5 15

And you might want to add an "extra vty" in case you need to actually telnet into the access server to clear a line.

But on my 2511 I see one session on vty 0 -- and then all my other sessions show up on ttys, not vtys. If I telnet in and then reverse telnet from there, I'm using a 2nd vty.

Are you telneting into the access server on each tab and then connecting to each of the other routers from there? Or do you telnet to the ip address of the access server AND the port number of the line to gain "direct access" to the remote router console port?

Here I have several connections to my lab routers by telneting to the access server ip and port number of the line I want to connect to -- those are the TTY sessions.

The VTY sessions are the 3 telnet sessions I did make to the 2511 (out of the default 5 I have configured).

R2511-2#

I have 7 telnet sessions through the 2511, 3 telnet sessions into the 2511, and 1 additional session from one of the 2511 telnet sessions another remote router.

good idea. thanks mike appreciate input. yeah I love my 2511 just i never knew how to have the multipe tabs until now with ctrl+shift, 6,x key combo from 2511 but i love the tabbed sessions so i can flip back in forth
via mouse click

love that i can have like 16 sessions and flip flip flip to each one trying new stuff fast...thanks will let you know how it goes

mikej

I am confused...very easy ;(

okay I want 16 tabbed sessions using my telnet gui program.
I have a 2511 access router that has 2 octopus cables
so 16 total asyn ports. but if I only have 0 to 4 vty sessions available
to me how can i take advantage of using a switch or teln thru my access router right? can you explain it to me thanks

mikej412

My access server 192.168.104.52. I telnet into that since the access server console cable is attached to an older laptop that has the built in serial port, not this newer and nicer laptop.

Then to access my R1 router from this laptop, I telnet to 192.168.104.52:2001
Then to access my R2 router from this laptop, I telnet to 192.168.104.52:2002
Then to access my R3 router from this laptop, I telnet to 192.168.104.52:2003
Then to access my R4 router from this laptop, I telnet to 192.168.104.52:2004
etc...

So you telnet into your access router 192.168.104.52
and telnet to each port that was configured with the reverse
telnet config? I will try that and see if it works not sure if i have my
access router configured correctly. will try it and let you know.
Sounds great though..be back soon....

No.....

You telnet directly from your PC/Laptop. As I said, I only telnet INTO the access server to monitor the lines or clear lines if I have a problem.

ALL telnets are from your PC/Laptop.

You use your access server's IP address that you can reach from your home network/pc/laptop.

telnet 192.168.104.52:2013
telnet 192.168.104.52:2014
telnet 192.168.104.52

That gives me access to my CCIE R&S lab routers, switches, back bone routers, frame switch, access server, and another router that accesses the Security/Voice/SP networks of my lab.

I see so mike look at below config I have so I edited
but normally I used the loopback 100.1.1.1. Is this wrong
should I use my ethernet port 192.168.15.217? subnet 15 is
my LAN subnet /24.. do I have it wrong or can I just telnet into
the 15.217:portnumber and it will work?
