simple uplink question: powerconnect 6248

Question

Hello,

I have an hp procurve switch uplinked to a powerconnect 5448. I want to disconnect the hp procurve, and configure the new powerconnect 6248 to uplink to the powerconnect 5448. I'm a networking newbie and so I'm looking to gather documentation in advance. When I look at the manuals and search the web I see references to using additional modules on the back of the 6248 to uplink. We don't have these modules. Is it possible to configure the 6248 to uplink using one of the ports on the front of the switch; can any of the ports give me an uplink?

It seemed to me, in my newbie naivety, that my question is straightforward, maybe it would be apparent if I just plug the switch in and access the GUI? So I did this, and compared some of the settings to the existing 5448. In the 5448, I see an option to designate a port as (PVE)Uplink. (Under Switch, Ports, Port configuration). I do not see this option in the 6248. What am I missing? Is the 6248 capable of uplinking out of the box? Or do I really have to buy an uplink module?

Much obliged for any assistance,

just for the record, I basically reset the switch and just plugged them together, it worked out of the box with default settings. This issue is resolved, thanks

Hi Daniel,

I did this on the 6248 as you indicate, no problem.

I tried to do the exact same thing on the 5448. When I get to the command: switchport trunk allowed vlan add 2

I get an error:

"VLAN 1: VLAN was not created by user."

Before I tried this command, the configuration looked pretty default (see below)

How can I get around this error?

Much obliged for your assistance,

Hi Daniel,

I've updated the firmware to the latest version.

These are the actual commands I'm entering:

console# config

console(config)# interface ethernet g6

console(config)# switchport mode trunk

console(config)# switchport trunk allowed vlan add 1

VLAN 1: VLAN was not created by user.

console(config)# end

There are no added vlans other than default vlan 1. We have only a small network and have not implemented vlans.

I understand the concept of Lag/port-channel/nic teaming or bonding from a server side perspective. My understanding here is that there is no bond in the picture, unless the uplink or connection between two switches is also called Lag/port-channel in networking terminology.

simon_tyler · Answer

Oh of course. The two switches are unable to ping each other.

Ok, then when I connect a laptop to the new switch and try to renew my dhcp lease, I don't get an ip address. I'm not sure what the next step in troubleshooting would be, this is a snip of the current config on the 5448

(it's the same as before with changes noted below):

interface port-channel 1

description UpLink

exit

port jumbo-frame

interface ethernet g6

switchport mode trunk

exit

voice vlan oui-table add 0001e3 Siemens_AG_phone________

voice vlan oui-table add 00036b Cisco_phone_____________

I'll go back to the 6248 and pull the config from that again.

Here is the current running config on the 6248:

console#show running-config

!Current Configuration:

!System Description "PowerConnect 6248, 3.3.1.10, VxWorks 6.5"

!System Software Version 3.3.1.10

!Cut-through mode is configured as disabled

!

configure

stack

member 1 2

exit

ip address 192.168.1.22 255.255.255.0

ip default-gateway 192.168.1.6

username "admin" password 124c9f87ed7e9f01b5563d162cc65b22 level 15 encrypted

!

interface ethernet 1/g1

switchport mode trunk

exit

the 6248 is using port 1 cabled to port 6 on the 5448. It appears to me that both interfaces are set to mode trunk. Not sure what's next?

Simon, you wrote: >5448 config: >port jumbo-frame I wonder if this might cause the trouble. I don't see this on the 62xx? Or isn't this necessary?
