I have set up a newly switch, cisco 3570C. Its in v15 and the only configuration i did is:
-set up interface ip add. 10.132.16.111
-set up telnet
I am able to telnet within LAN environment. I cant ping or telnet the switch in a WAN enviornment. Is there any setting i should confgure on the switch?
I 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?
I only want SSH to be allowed when accessing this switch, but telnet is still allowed, why?

View 4 Replies View RelatedWe 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. In the direct connected network device such as access switch and ASA , can't ping or telnet the 4507R too. when we made a forceswitch to sso standby supervisor from console , the problem solve and everything get fine . after that, we switch angin back to the origin supervisor , fine 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.
I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50
10.10.50.0/24
SITE B - Cisco 3750 L3 - VLAN ID 50
10.20.50.0/24
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.
I have aaa new model configured on a number of isr's(1800, 1900, 2900, 3800 etc). When i have aaa configured, the telnet logins use that authentication and not the password in the line vty portion. Is this by design. would disabling aaa enable both telnet and aaa authentications, essentially making it a dual login.

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.
I am trying to Disable Telnet and enable SSH in CatOS for 6500 .
View 12 Replies View RelatedI 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?

View 1 Replies View RelatedI have a catalyst 3550 and will be using it to run my cisco 7940 and 7960 ip phones with POE. 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.
What I need to do to get everything set up correctly?

View 6 Replies View RelatedI'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?
Any 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!
I have a network with 3 sites that are on different subnets. Each site has an ASA Right now, I am only able to connect to the ASA that is connected to the subnet I am connected to.I want to be able to connect to the ASA that are on the remote subnets on the address of the inside interface.The sites are connected all together by site-to-site VPN.Is there any way I can achieve that without opening the outside interface directly on the Internet?

it is possible to capture user who execute ‘Telnet” or “show line” in the log, I mean all the command entries by user.
How to enable any config on 2911.
The 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.
I have configured the ip telnet source-interface Loopback 0 command on a Nexus7010, but when I telnet to another device and do a show users, the ip address is of the closest interface to the device I telnet to, not the ip address of the Loopback. All interfaces are in vrf default. I am running 5.1(6) NXOS.

I know these are no longer supported, but I have to ready them for migration. Recently a problem began with these switches. What happens is that when I telnet to them, I cannot authenitcate via TACACS. This works fine for all our other IOS equipment, just not for these 2 switches. The error is:" % Error in authentication" and then I get kicked back to the login prompt.
The odd thing is that when I connect to the switch via the console port, I can authenticate fine with TACACS.
