GSM7352s connecting to GS724/48 VLAN Routing issue

[Old_Nick66]

Using a GSM 7352s as core with VLAN Routing to GS724TP.
Multiple VLAN's set up and working However we lose the Web management interface on the GS724 when we Tag the trunk port for the VLAN.

GSM7352 connects from Port 25 to Port 1 on the GS724 (Port 26 will eventually connect to another switch in the same Subnet)
VLAN 5 is used for IP Telephony using option 43 in DHCP

GSM7352
VLAN 1 192.168.80.254 all ports U
VLAN 5 192.168.0.254 port 25 / 26 T 29-46 U
VLAN 10 192.168.202.10 port 25 / 26 T


GS724TP management IP 192.168.202.202
VLAN 1 All Port U
VLAN 5 Port 1 T
VLAN10 Port 1 T

If I recall early firmwares for the GS724/48's did not support changing the management VLAN from the default (1). I would suggest, at first glance, checking your firmware versions on the GS724's, and then set the correct management VLAN (5?) on the GS724's
