Symptom
Connectivity loss to PCs in data vlan when connected to ports on a EHWIC-D-8ESG-P.
PCs do not get IP address from DHCP server.
Conditions
Issue noticed when the EHWIC-D-8ESG-P interface is configured in the following order (portfast prior to voice vlan):
Router(config-if)#switchport access vlan 100
Router(config-if)#spanning-tree portfast
Router(config-if)#switchport voice vlan 101
Workaround
Remove the portfast and voice vlan configuration and re-apply voice vlan prior to portfast.
NOTE : if the router is reloaded it is possible that the portfast is applied first leading to the connectivity loss.
