I'm using a 3560 switch. The switch is set up with 10 vlans. Devices on vlan 3,4 and 5 are talking to each other through intervaln routing (done by the swtich itself). I'm able to ping devices on vlan 5 from my unit on vlan 4 and data are being routed without any problem.
What i'm not able to do is telneting those devices from my unit which is again on vlan 4.
i know that enabling DHCP between vlans needs the command ip helper-address, wondering if i need to do something similar to enable telnet between vlans.
There is no need to setup helper addresses to get telnet working.
Indeed it sounds like routing is working correctly, as your able to ping from vlan4 to vlan5 without issue. I'd suggest that it's time to break out the ethereal or equivalent packagage and look at the devices to ensure that not only are they listening for telnet connections, but they are responding appropriately.
as suggested jon.marshall you are able to telnet with in the lan/VLAN.
1. Is this a new setup with 3560 swith with 10 VLANS
2. Was this working earlier in the current setup with 10 VLANS and intervlan routing.
4 What are those devices to which u r telneting.
5 I suspect somet type of access restriction is at place on those device/application which alows telnetting from its own network but not from the remote network i;e VLAN3,VLAN5 etc except for VLAN4 which is in same network.
kindly check the device/application running telnet service
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
