HP Procurve 2824 1

[ceil32]

I have a new HP Procurve 2824 - 24port

It's plugged into a rack with an old 3com 10/100 and a Gigabit Cisco

I've connected it to both existing switches and get a link light when I do so.

I've patched in some new network points to this switch, but when I connect a client to the new points, it doesn't receive any data

Do I need to do any config on the switch (as it's effectively out of the box)

Or if not, what ports should I connect it to the existing switches on?

Thanks..

Hi !
Yes I think you'll need to get some RS232 cable and do some configuration

Later you could play with it on WEBBASED interface, but I think first you'll need to set up some stuff...

For an easier interface just type MENU in the console

Ok I've logged in with an RS232 cable and done the following:

Assigned a name, password, static IP addy for the switch and the default gateway as used by all LAN devices.

I've saved, rebooted switch and I've still got limited connectivity when I connect a laptop to any port on the switch

Can anyone help?

thanks

Based on the information you have provided it makes it hard to diag.
Whats the topology of the network ?
Is there more than one subnet defined on the network?
Do you have a DHCP server? Is it in the same Subnet?
What model Cisco are you connecting it to?

You are getting " limited connectivity" becuase the workstation is not receiving it addressing from DHCP, Meaning the problem lies in the configuration of your switches.

Sorry should've been more specific:

Only one subnet - Class C - 255.255.255.0

DHCP Server with a range of twenty addys on same subnet

Cisco switch is a Catalyst 3560

Can you advise what port I should connect to Procurve to and from -> Cisco

Thanks..

It sounds like (if the Cisco is configured right) that all switches ports are in a single VLAN instead of using the default VLAN. If that is the case what you will need to do is on the switch port that the HP is connected to on the Cisco is make sure that it is set as a trunk port with dot1Q as the encap type. Then on the HP create the same vlan as what the Cisco has (VLAN ID ) and add the switch port coming from the Ciso to the HP as a "tagged" port in that vlan, with all other ports being untagged in that vlan.

Example

Cisco 3560
Switch Port 24
Switchport Mode Trunk
Encapsulation dot1Q

**Example VLAN 36****

HP 2824
Create VLAN 36 (or whatever it is on the Cisco)
Port 1 (uplink to Cisco) Tagged in VLAN 36
Ports 2-24 untagged in VLAN 36

Hope this helps. If you are unsure of the Cisco commands let me know.

If you advise the commands required thanks!

 

[MrNick0483]

Telnet (switch IP)
enable

show vlan (you will be able to see what vlan your cisco is using, and what ports are in it)

ciscoswitch# conf t
ciscoswitch(config)# interface fa0/24
ciscoswitch(config-if)# switchport
ciscoswitch(config-if)# switchport mode trunk
ciscoswitch(config-if)# switchport trunk encapsulation dot1q

exit
write mem

When I issue show vlan on the Cisco, there are four VLans displayed - only the first one is active

All the client ports seem to be in use on VLan 1 - Ports go from Gio/1 upto Gio/52

Conf t - works fine

interface fa0/24 - get the following error - % invalid input detected at '^' marker

 

[ceil32]

I get as far as 'switchport mode trunk' and get the following:

Command rejected: An interface whose trunk encapsulation is "auto" cannot be configured to 'trunk' mode

 

[ceil32]

Ok I've got all those commands successfully issued and saved

Can anyone help me with the necessary commands needed for the HP Procurve?

 

[ceil32]

Anybody??

 

[cpx13]

just enter the:

switchport trunk encapsulation dot1q
before entering
switchport mode trunk
