Trunking Two 6248's -- going banananananaanas :)
Hello,
Help. I'm trying to trunk 2 6248's together. One is the main (distribution) switch, the other is just a L2 (access) switch. Actually, I'd like to make them into a stack, but they are separated by a single copper cable in 2 different closets. - Is there a way to still make them a stack?
Anyway, what I need help with right now is that I can't seem to get trunking working properly. I've been doing some digging in these forums and it seems that everyone is tagging stuff. I don't want tag, I'm using L2 (access) VLANs. Not *.1q tagging.
In the Cisco world I believe they call this VTP (VLAN Trunking Protocol). Looks like GVRP is similar but is relating to Tagging again.
I have about 6 L2 VLANs...
VLAN 10, 20, 30, 40, 50, 99
Want to trunk on port 1/g48..
switchport mode trunk (on both switches)...
But I can't say, switchport access vlan 30 on the second switch.. Not until I go into the vlan database on the second 6248 and create all the VLANs on the main 6248. I was hoping the main 6248 would advertise its VLANs to the second 6248. Which I guess can happen if I was to do tagging.
I've also gone through and done the switchport trunk allowed vlan add yada yada yada business, even added it as a test on both trunking interfaces... Although the show commands would show the trunk ports as members of all the vlans as well as the ports I assigned in the second 6248, I still could not ping a host on VLAN20 on the main 6248 from VLAN30 on the second 6248. I couldn't even ping it when the VLANs were the same (VLAN20) between switches. Is there a way to do this without tagging?
Unfortunately, I do not have the configs with me. I can get them though.
I am pressed for time and pressure is building - the company is moving in to the new space next week. VLAN routing on the main switch works fine, fyi. :) Need to get this working ASAP.
I just want the ability to go into the second 6248 and assign a port to a VLAN...
switchport mode access
switchport access vlan 30 (or whatever vlan)
The next issue I have yet to test is DHCP and helper addresses. Sure hope this works the way I have it set up....
Thank you!
Fixed the DHCP issue. I had to turn on Admin Mode under Routing->BOOTP/DHCP Relay options in the WebGUI.
Yeaaaa
ok now to figure out how to get to the second switch via telnet/http.
I guess what the question is, how do I get to the management vlan?
The management vlan is vlan #1. You will need to to trunk this vlan across the switches, and remember it cannot be routed. Now as for your whole vlan/tagging issues. you keep mentioning that you are running flat layer 2, yet you list multiple vlans on the main switch. You must use tagging to pass more than 1 vlan between the 2 switches on the trunk port, they go hand in hand. I also see in your configs you have channel groups configured, which really dont do you any good as you only have 1 port in each channel group. This also may be causing issues with your vlan tagging as you would have to tag all the vlans you want to pass over the trunk port under "channel group 1".
Just my 2 cents

Now just need to get DHCP working across VLANs... Why isnt this working??
And I'd like to figure out how to login to the second 6248 remotely.
