Hello Everybody, I'm having some issues with Telnet sessions that are hunging up in a cisco 6509, on the line vty mode the command exec-timeout is already configured, otherwise the commands service tcp keepalives are not configured on the switch, i think this may be the issue, but i don't know what consecuences might happen if we configure this commands because this is our core switch, it carries all the vlans of the company, could anybody tell me if this commands must be applied in this situation or because this is the core switch no tcp keepalives packets must be sent?
