Cisco Switching/Routing :: Upgrading Newest Software Images On C2950G Switch
Jan 23, 2012I was upgrading the newest software images on a c2950G switch. So i followed the step by step procedures from url...I removed the current flash that was on the switch and then for some reason typed reload. This started the switch up without the IOS. Make a long story short I am now stuck in switch: prompt mode and I am unable to use x-modem to transfer the newest IOS onto the switch. I am currently getting "no response remote system".

Sep 30, 2012We use C2950G switches with IOS 12.1(22)EA12 . Switches are set up to send logs to a server (informationnal level). On this server, we receive many of logs from those switches, but none about interfaces errors (even if interfaces statistics show interfaces errors). On C3548 switches it's work fine.How should I be sure the set up of switches is correct ? Why do I never receive messages as %LINK-4-ERROR:[char] is experiencing errors ?

Cisco Switching/Routing :: 2960-S - Can't Telnet / Ping Into Switch
Sep 4, 2012I have a Cisco 2960-S Switch, It is connected to a jack in the building to check the settings, Interface VLAN 1 has an ip, there is a default gateway, Any host connected to switch can access the network resources. But the problem is that I have to use Serial Cable to configure it. I cant ping or telnet into it from any other device. PC's are on different subnets/VLANS.
Basically this switch is connected to a port in a different switch, Do i have to make a trunk?

Cisco Switching/Routing :: 4507R-E / No ARP Virus - Switch Can't Response Ping And Telnet
Apr 10, 2012We got a switch issue here for 4507R-E with two sup6l-e supervisor running sso redudant. and we found that sometimes client can't ping through the local vlan ip add on the switch , can't logon the cli by telnet too.

before we made the supervisor forceswitch , we had check the system cpu usage is 15 - 20 % from console . also we had creat a new vlan 200, attach the notebook to 4507's vlan 200 port , the notebook can't ping or telnet the vlan 200 ip interface too.

the intent of the above is that management connections will only be accepted via SSH, and all of those will be authenticated via RADIUS, unless it's down, then it will use the local username/pw combinations, most of which are given Privledge level 15. Telnet should never work.SSH works as expected (authenticates via RADIUS), but the problem is that Telnet also works, will ONLY use the local database (never RADIUS), and, for some reason, leaves the users at Privledge level 1, instead of the configured 15.Essentially, it seems that at every point I have told it to do something that isn't the default with regards to telnet, it ignores me.Prior to a recent IOS upgrade, the switch didn't support SSH, so the previous config was Telnet with RADIUS, and that worked fine.

Dec 21, 2011I have a new 877 that I am using for internet traffic for 3-4 internet only devices.I also have a clean network that i want to insure no cross contamination. However I plan on rolling this out to many sites, but for management I was hoping to set up a reverse telnet to the console port from our one of my clean switches. which should allow me to keep the units seperated and allow me to manage changes etc remotely. Unfortunatly there is no Aux port on the clean switch (3560). Is there still a way to acheive this? can i configure one of the ethernet ports to connect to the console of the 877?

When I plug the phones into the switch they power up just fine but the phones will not dial out as they have little x's by the line. I have also tried going through the set up of the 3550 but get stuck in one place. When I go to the 10.0.0.0, the screen will not allow me to enter the telnet page or allow me to enter any information. In the manual it shows a pic of what the screen should look like when I go to 10.0.0.1, but I am getting an entirely different page.

Dec 18, 2011I'm using a radius server to authenticate ssh when connecting to my company's switches (a 3560 + several 2960s).
Everywhere I've looked claims that using the line 'transport input ssh' in my switch config should disable telnet access and allow ssh only. But after changing 'transport input ssh telnet' to 'transport input ssh' I can still connect to all of the switches from telnet. I can't block telnet with ACLs either because my company uses a telnet based terminal client to do most of their work.
I don't have much experience with radius. How do I stop telnet connections when using radius to authenticate?
Cisco Switching/Routing :: Pasting Script Into Nexus 7000 Telnet Session?
Feb 27, 2013Any issues with pasting scripts into a Nexus 7K and having the scripts get all messed up even though they are logically correct? I've had this issue over the years with IOS devices and the console port and tweaking some of the line feed/character delays fixes the issue but that was always with the console port and not a telnet session. Telnet has always worked flawlessly on IOS.
I've determined that if I tweak my line feed delay up to 1000ms it seems to work fine, but it just doesn't make sense to me that I have to do that.I have a customer with 3300 ACL lines that need to be put into a Nexus as part of a migration from 6500 to Nexus. And yes, I've already tried to convice them to offload these VLANs behind an ASA!

Cisco Switching/Routing :: Unable To Ping VPN 3005 Concentrator From Telnet Session In 3750
Feb 7, 2012The network is set up like this.
Host -----> 3750 (classic) running IPSERVICES stack ----> 3550 router -----> VPN 3005 Concentrator.
IP routing is disabled on the 3750 (it's acting solely as a switch) IP routing is enabled with an EIGRP process running on the 3550 router that has the network for the 3005 broadcasting.
I can ping the vpn 3005 concentrator from a telnet session in the 3550 but not from the 3750.I can ping between the 3750 and the 3550 vlan management interfaces. Visually speaking it's like this
3750 ------> 3550 [Success!!!!]
3550 ------> VPN 3005 Concentrator [Success!!!!]
3750 ------> 3550 --xxxx--> VPN 3005 Concentrator [Timeout....]
I know this because I tracerout to the 3005 from the 3750 and it resolved the default gateway configured for the 3550 properly but then started timing out.
The 3750 is trunked to the 3550.
3750 is vtp client mode
3550 is vtp server mode
I'm wondering if there's a layer 2 issue involved here as it is a VTP domain and maybe it's not returning properly.
