Initial Connection Delay

An IP address and default gateway is optional on a layer 2 switch, and are only used to connect to and configure it, correct? If true, then a switch that is configured for 1 network can be moved to another without making any changes.

Trying to troubleshoot an issue where Citrix ICA clients are taking 3 minutes to get the logon screen. After they get the logon screen, the can exit, try again, and it takes only 3 seconds. If they reboot, they again must wait 3 minutes to get the logon screen. After they logon, all is well. There is a Raptor firewall (Solaris) between the Citrix server and the clients. If a client moves to inside of the firewall, it takes only 3 seconds to get the logon screen. There is a switch that has an IP address that is outside of the network on which it is attached, sitting between the firewall and the Citrix server, but the initial delay appears to be a firewall issue. Ideas?

Re: Initial Connection Delay

What switch is it? paste sh ver from it. Also does the client ports have port-fast enabled? Take a look at the following page

Siwtch ip address has nothing to do with it forwarding mechanism, it is only for the management purpose, so that you can able to do remote management to the switch. Even if you don;t assign the switch any ip address it' ll be still forwarding the ip addres.

The problem you are describing seems like the firewall issue. Please look at the port counters and making sure if there isn;t anu speed/duplex mismatch between the switch and the machines directly connected on the switch.

Please use the set port host command( only for the switches running CATOS) to the devices connected to the server or workstations or the firewall which is not doing any bridging. It enables portfast and turn off trunking and channelling on the ports.
