How to expand internal network for Cisco 4948E?

[tmq626]

Hello,

I have setup an internal network for my Cisco 4948E switch as below:

---

switch#enable

switch#conf t

switch(config)#service dhcp

switch(config)#vlan 10

switch(config-vlan)#name TMQ

switch(config-vlan)#exit

switch(config)#int vlan 10

switch(config-if)#ip address 10.0.0.1 255.255.255.0

switch(config-if)#do write memory

switch(config-if)#exit

switch(config)#ip dhcp pool TMQ

switch(dhcp-config)#network 10.0.0.0 255.255.255.0

switch(dhcp-config)#default-router 10.0.0.1

switch(dhcp-config)#dns-server 10.0.0.4 10.0.0.5

switch(dhcp-config)#lease infinite

switch(dhcp-config)#do write memory

switch(dhcp-config)#exit

---

Now, this Cisco 4948E switch is full. I would like to expand this internal network by using Cisco 2960G connecting to one port of Cisco 4948E.

What should I config for Cisco 2960G so that it works with this internal network?

Thank You!

On 4948 take 1 free port to configure as Trunk :

For example: the same config applies on both the switches.

(config)# interface gig 1/0/1   <<-- change this to free port
(config-if)# switchport mode trunk
(config-if)# no shutdown

On 2960 - do the basic config and create the required VLAN (hope you do not have VTP in your network) to make VTP transparent.

do the same config as mentioned on the required port.

connect RJ 45 patch lead,

make one of the ports required access VLAN (if not vlan 1)  

Test it

Can you please verify if below setup is correct:

1) Connecting port#48 on 4948E to 2960G uplink port

*Configure below for 4948E - Port#48

(config)# interface gig 1/0/48
(config-if)# switchport mode trunk
(config-if)# no shutdown

*Configure below for uplink port of 2960G

(config)# interface gig 1/0/48
(config-if)# switchport mode trunk
(config-if)# no shutdown

* Configure port# 1 -> 44 of 2960G to access mode.

Thanks

Can I just connect an unmanaged HP switch to 1 port of Cisco 4948E and the internal network will automatically work on HP switch?

Thanks

Not sure what is the model of the switch of HP you need to refer to that guide 

you like to extend 1 VLAN - All VLAN

Try always trunk port as suggested above config and test it, if not working change the port to access model should be good.

That HP switch is HP Procurve 1410-24G

Thanks

The trunk should work -(as I mentioned this need to test)
