Trunking between PC6248 stack and PC5324
The end goal of my project is to set up guest internet on PC5324 port g1 with a WAP on vlan 172 with no access to other vlans. Other ports on the PC5324 will belong to vlan 11. As the first step I created a trunk on PC6248 port 1/g7 and added vlan 11 and 172. I created a trunk on PC5324 port g21 and added vlan 11 and 172. I added PC5324 port g3 to vlan 11 and connected a laptop. I added PC5324 port g1 to vlan 172. Vlan 1 is the management interface (192.168.11.1 /24). CAT5e connects PC6248 1/g7 to PC5324 g21. The next hop for vlan 11 from the PC5324 is 192.168.11.254 (vlan 11 on PC6248 port 1/g7). From the PC6248 I can ping 192.168.11.254 but not 192.168.11.1. From the PC5324 I can ping 192.168.11.1 but not 192.168.11.254. I tested the cable and ports as the source of the disconnect. Can someone help me discover what I'm overlooking? The config information is listed below for both devices.

General links are mostly used today for legacy equipment. However, on the PowerConnect 62xx series switches, you must use General mode if you want to allow management traffic onto the switch over the PVID. If you use Trunk mode, you will not have the default VLAN on those ports. The ports will only allow tagged traffic. So I would suggest changing from Trunk to General mode and set the PVID to 1.
console(config)# interface ethernet 1/g7
console(config-if)# switchport mode general
console(config-if)# switchport general allowed vlan add 11,172 tagged
console(config-if)# switchport general pvid 1
console(config-if)# end
Once that is changed you should be able to ping between the switches.
Thanks

Thank you for your help with this issue. I can ping both directions on both vlans (11,172) but not the management interface (VLAN 1 192.168.11.1 /24) on the PC5324. I can access the PC5324 through the console. Listed below are the ping results from a Windows command prompt and from putty. The putty results are opposite from the Windows results. How can I establish remote access to the PC5324 on vlan 1?

That looks great on g7, lets go to the 5324 and do the same configuration on g21. Then do the show interface command on g21, make sure they look the same. Then test for the connectivity. Other than that I am not seeing what might be causing this to occur, but I will continue looking into it.

I have been looking back through the information we have here to try and identify any other suggestions, but not finding anything with what we have. The next step is to get a full running config from each switch. I can look through the entire config for any possible suggested changes.
If we plug another workstation/laptop into the 6248. Can we ping from workstation to workstation on VLAN 1?
Thanks.

What is the best way to get the full config to you? The PC6248 config is many pages and I'm concerned about security if I post the config for my datacenter core on an open forum.
