Hi Ganesh,

I will be using the E5oo cat switch for additional connectivity of the systems and IP phones. Since I am falling short of ports on 4500 switch.

Can I connect 500 and 4500 switches without configuring the port as trunk...If I simply connect the E500 cat switch to 4500 switch with a cross over cable..will E500 cat switch come up? Will the system connected on E500 switch port take an IP address?

Hi Amit,

Thanks for looking into this.

I have a data and voice vlan in 4500 series switch.

Hi Syed,

You can if you wanrt to but you don't need to use crossover cable, you can just use stright through cable.

Once both sides are connected do "no sh" under each interface, they should both come up if the cable, the port and the module are all good.

Hi,

You can connect with straight through cable also if that port is connected to same vlan as of E500 switch then it will work.

Hi Reza,

I am using a cross over cable to connect these switches.

I have a data and voice vlan in 4500 switch for system and IP Phone connectivity. I am falling short of ports so i am extending the connectivity with E500 swicth...Do i still need trunk??? If i don configure trunk then atleat system connected on port of e500 switch sohuld take an IP ....right?

You need a trunk for both the data and voice vlan to travel across the switches. If you connect it to data vlan then the PC will get the IP without any problem. You can either use a cross-over cable or a straight through cable as most the switches today comes with MDIX feature.

Hi Syed,

Since you have 2 vlans go ahead and trunk the port

here is a sample config:

switchport trunk encapsulation dot1q
switchport trunk native vlan 3 (Data VLAN)
switchport mode trunk
spanning-tree portfast trunk
switchport trunk allowed vlan 4 (Voice vlan)

Amit is right you need to have trunk between the two switches for both data and voice traffic to flow.

Hi,

I have connected the E500 switch using a straight through cable to 4507 switch. The port at Cisco 4507 is showing as connected but the system connected on E500 switch is not taking an IP address from DHCP. The system shows an IP address 169.X.X.X. How to connect these switches and how to bring the systems in network which are connected on E500 switch???

Pls help..

Are the ports on both switches in the up and up position?

on both switches what does "sh ip int brie" shows?

here is an example:

Switch#sh ip in bri gi1/0/1
Interface              IP-Address      OK? Method Status                Protocol
GigabitEthernet1/0/1   200.200.200.1   YES NVRAM  up                    up     
Switch#

Hi Reza,

The status of the port at the Cisco 4507 switch is

Switch#sh ip int brief g 7/21
Interface                        IP-Address      OK?      Method      Status                Protocol
GigabitEthernet7/21         unassigned      YES      unset       up                    up

But i don know how to check the status at E500 switch. it doesn't have any console port also.
