problems connecting a powerconnect 5224 and 5324

Question

Hi,

I have a powerconnect 5224 and i am trying to connect it using port channel to my 5324. the 5324 is fine, all setup and working. but im having problems configuring the 5224.

Two problems:

Fistly i have setup 3 Vlans for testing purposes and i can only set an ip on one. when i try to set the secont ip on the second vlan, some how wit will remove the first vlan ip and replace it with the second like so:

interface vlan 100
ip address 10.100.100.1 255.255.255.0

then replaces it with this:

interface vlan 200
ip address 10.200.200.1 255.255.255.0

Secondly, i cannot figure out how to setup the port channel at all!!!!!

im using the CLI

Thanks for the help.

still not having much luck with the port channel after following your instructions. I cannot ping any of the Vlans over the trunk. I have supplied the config for you to look at and hopefully comment on.

building running-config, please wait.....

The PowerConnect 5224 will only support a single IP address, unlike the PowerConnect 5324 which will support up to 4.

On the PowerConnect 5224, the port-channel must be instantiated prior to adding an interface into the group. In addition, only a single interface may be configured into a port-channel at a time.

console# config
console(config)# interface port-channel 1 << Creates the port-channel
console(config-if)# exit

The following is a link to the User's Guide for the PowerConnect 5224 that outlines how to configure a Link Aggregation Group.

ok, i have removed the 5324 and i am now working with 2 5224's.   I have managed to get the LACP trunk working and from the two switches i can ping each other.  The problem now is that i cannot ping from device to device over the link or from the swith it the remote device.    Any ideas? Oh and both switches have the same config except the ip addresses.

DELL-Randy · Answer

Per your posted previous configuration -- You have created a port-channel, configured the port-channel to operate in trunk mode, and created your VLANs within the VLAN database. However, you have not assigned the VLANs to the trunk.

As you have assigned your access ports into the respective VLANs (ethernet 1/1-3), you must now assign the port-channel into the VLANs as well in order to pass the 802.1q information. In the instance of LACP, you must determine the port-channel ID in use to assign the correct ID into the VLANs.

console# config
console(config)# interface port-channel N
console(config-if)# switchport allowed vlan add n,n,n tagged
console(config-if)# exit

VLAN Assignment --

Thanks for that Randy but still no luck. I have tried to make things a little simpler now and i have removed the Vlan's. i have exactly the same config on both switches and i still have the same problem that i cannot ping from device to device and i cannot ping from switch to remote device. Here is my new simpler config:

Thanks for that. I managed to sort it about an hour ago. All i did was boot to the factory defalt and then add the port channel and trunk again. this worked forst time without any problems. I have printed the new config off and compared it to the old and they are exactly the same! Very annoying but at least we got it working hey!

cheers for all your help.

Interesting indeed.  If possible, I would configure the PowerConnect 5224 to boot to the Factory_Default_Config.cfg file and delete the startup-configuration file on the PowerConnect 5324 with the command -- console# delete start.   When each unit has been successfully rebooted, configure an IP address and attempt to communicate between the devices with this initial configuration.  Then, configure the port-channels on each device and attempt the communication again.  Now configure the port-channels to be trunks and, once again, verify connectivity.  If after configuration of the port-channels you are unable to communicate, please verify the mode type in use on the PowerConnect 5324 as it should be 'on' for static groups or 'auto' for LACP.
