I solved this by setting the uplink port to general, which eventually solved the issue
Hi, We have 2 x PC6248 which we want to configure as a failover setup. Our servers have NICs with cables in each switch. On our network we have 5 seperate VLANs VID1: Private VID2: WAN VID3: iSCSI VID4: LiveMigration VID11: DMZ  Uplink will be 1/g48 (later on I will create a LAG with more ports) on each switch, and is configured: interface ethernet 1/g48switchport mode trunkswitchport trunk allowed vlan add 1-4,11 All my ports in my 5 VLANs are Untagged. Problem is that everything works fine on switch1, but I cant get connectivity to switch2 (management interface and so on) Any suggestion what I do wrong? Here is complete config of switch1: !Current Configuration:!System Description "PowerConnect 6248, 2.2.0.3, VxWorks5.5.1"!System Software Version 2.2.0.3!configurevlan databasevlan  2-4,11exithostname "switch1"stackmember 1 2exitip address 10.110.1.3 255.255.255.0ip default-gateway 10.110.1.1access-list testinterface vlan 2name "WAN"exitinterface vlan 3name "iSCSI"exitinterface vlan 4name "LiveMigration"exitinterface vlan 11name "DMZ"exitusername "frkirene" password xxx level 15 encryptedflowcontrol!interface ethernet 1/g1switchport access vlan 2exit!interface ethernet 1/g2switchport access vlan 2exit!interface ethernet 1/g3switchport access vlan 2exit!interface ethernet 1/g4switchport access vlan 2exit!interface ethernet 1/g5switchport access vlan 2exit!interface ethernet 1/g6switchport access vlan 2exit!interface ethernet 1/g7spanning-tree portfastswitchport access vlan 3exit!interface ethernet 1/g8spanning-tree portfastswitchport access vlan 3exit!interface ethernet 1/g9spanning-tree portfastswitchport access vlan 3exit!interface ethernet 1/g10spanning-tree portfastswitchport access vlan 3exit!interface ethernet 1/g11switchport access vlan 3exit!interface ethernet 1/g12switchport access vlan 3exit!interface ethernet 1/g13switchport access vlan 3exit!interface ethernet 1/g14switchport access vlan 3exit!interface ethernet 1/g15switchport access vlan 3exit!interface ethernet 1/g16switchport access vlan 11exit!interface ethernet 1/g17spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g18spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g19spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g20spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g21spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g22spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g23spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g24spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g25spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g26spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g27spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g28spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g29spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g30spanning-tree portfastswitchport access vlan 11exit!interface ethernet 1/g31switchport access vlan 4exit!interface ethernet 1/g32switchport access vlan 4exit!interface ethernet 1/g33switchport access vlan 4exit!interface ethernet 1/g34switchport access vlan 4exit!interface ethernet 1/g35switchport access vlan 4exit!interface ethernet 1/g36switchport access vlan 4exit!interface ethernet 1/g37spanning-tree portfastexit!interface ethernet 1/g38spanning-tree portfastexit!interface ethernet 1/g39spanning-tree portfastexit!interface ethernet 1/g40spanning-tree portfastexit!interface ethernet 1/g41spanning-tree portfastexit!interface ethernet 1/g42spanning-tree portfastexit!interface ethernet 1/g48switchport mode trunkswitchport trunk allowed vlan add 1-4,11exitsnmp-server community public rw ipaddress 10.110.1.41exit
