we have an HPE 1920 PoE switch connected to a Cisco 1841 router, vers 12.4. The HP switch has two VLANs:
- Data - VLAN 1 - 192.168.50.0/24
- Voice - VLAN 55 - 192.168.55.0/24
The port on the switch that uplinks to the router has VLAN 1 untagged and VLAN 55 tagged.
The router has two subinterfaces configured:
interface FastEthernet0/1.1 encapsulation dot1Q 1 native ip address 192.168.50.254 255.255.255.0 no snmp trap link-status no cdp enable ! interface FastEthernet0/1.55 encapsulation dot1Q 55 ip address 192.168.55.1 255.255.255.0 no snmp trap link-status no cdp enable
show vlans on the router shows No Virtual LANs configured.
There is connectivity on the default VLAN okay but not for the second VLAN, I'm not even able to ping the .55 subinterface from the switch.
Is there a way to get this working please?
