Power Connect 5424 Trunking between to Dell switches

This should work.

Switch 1:

config

interface ethernet 1/g23

classofservice trust ip-dscp

switchport mode general

switchport general allowed vlan add 10,20,30 tagged

lldp transmit-tlv port-desc sys-name sys-desc sys-cap

lldp transmit-mgmt

lldp notification

lldp med transmit-tlv location

lldp med transmit-tlv inventory

exit

This will allow VLANs 10,20, & 30 across the trunk link.

Also it needs to to be identical on both ends (ports) of the trunk.

Switch 2:

config

interface ethernet 1/g24

classofservice trust ip-dscp

switchport mode general

switchport general allowed vlan add 10,20,30 tagged

lldp transmit-tlv port-desc sys-name sys-desc sys-cap

lldp transmit-mgmt

lldp notification

lldp med transmit-tlv location

lldp med transmit-tlv inventory

exit

Thank you, I have one more question. Do I need to make any changes to the,

port jumbo-frame

interface range ethernet g(1,24)   (Change to this (1,23,24))????

switchport mode trunk

I just wanted to know if I need to add port 23 on this switch anywhere else or will the above commands you have given do this for me.

Thank you for your time.

Jumbo frames are generally any frames with sizes above 1500 or 1522.  Unless you are using iSCSI or some other advanced technology across these links, jumbo frames shouldn't be required.  Standard Ethernet frames should be well under this limit.

The config that I sent you has Switch 1 port 23 connecting directly to Switch 2 port 24.

At least that is what I thought you were trying to achieve.

And the config only allowed VLANs 10,20,and 30 to go across the trunk.

If you want to trunk to other switches using other ports, you should configure those ports like these.

>switchport mode trunk

There are 3 port modes in the land of Dell.

1. switchport mode access

2. switchport mode trunk

3. switchport mode general

If these were Cisco switches, I would tell you to use "switchport mode trunk."

However since these are Dell switches, the "switchport mode general" command is a bit more flexible.

On switch to switch links/trunks and ports that have Voice over IP phones with PC hanging off them, I prefer to use switchport mode general like in my example.

On ports that just have only host devices connected to them, I prefer to use the commands:

switchport mode access

switchport access vlan xx

Alright, looking into this further, on switch 1 we have port 24 trunking to another switch 3. Is there a simpler way to add port 23 on switch 1 to also trunk without changing or adding additional commands? Here is the layout,

Switch 1 trunks through port 24 to switch 3

I need Switch one also to trunk from port 23 to switch 2 on port 24.

Can't I just add port 23 on switch 1 with a simple command?

Thank you

uh, forget this post from me ...

Thilo

I believe I need to remove port 23 from the command, interface range ethernet g(17-23)  to say g(17-22)

then I should be able to use the command,

port jumbo frame

interface range ethernet g(1,23,24)

switchport mode trunk

This would add port 23 as a trunk correct?

Thank you.
