e.Besides trunking, what are the other modes for which a switch port can be configured?
_____________________________________________________________________________
f.From enable mode verify the port is properly configured as a trunk port by using the show interface
CMESwitchX# show interfaces fastethernet 0/1 switchport
g.What is the status of the switch port (shown as switchport in the command output)?
_____________________________________________________________________________
h.What is the status of the Administrative Mode? _____________________________________
i.What is the status of the Operational Mode? _________________________________________
j.What is the Operational Trunking Encapsulation that has been configured? _________________
k.What VLANs are trunked by default? _______________________________________________
l.Some switches have another command that can be used to verify trunking
CMESwitchX# show interfaces trunk
m.If the show interfaces trunk command is available, what port(s) have trunking enabled?
_________________________________________________________________
n.If the show interfaces trunk command is available, what VLAN is the native VLAN? (Note: The native VLAN is the VLAN that does not tag a frame from this VLAN as it traverses the trunk with VLAN information. It is also the VLAN that continues to cross the link between the router and the switch if the trunk ever fails for any reason.) _________________________________________
o.If the show interfaces trunk command is available, what VLANs are allowed on the trunk based on the output from this command? _____________________________
p.If the show interfaces trunk command is available, what VLANs are participating in spanning tree and are in the forwarding state? ______________________________
Step 13 Test connectivity across the trunk
a.From enable mode on the switch, ping the router IP address for VLAN1 (the management VLAN). Refer to IP Telephony Table 1 for this address. (X in the command below refers to the pod number.)
CMESwitchX# ping 10.X.0.1
b.Was the ping successful from the switch? _____________________________________
If the ping was unsuccessful, do not proceed until appropriate troubleshooting has been performed and the ping is successful. Note that on some models of routers and switches the speed and duplex must be manually configured on both ports.
c.Ping the router IP address for the voice VLAN and the data VLAN. Refer to IP Telephony Table 1 for IP addresses, if necessary. All pings should be successful when the trunk is working correctly. Troubleshoot as necessary.
