Dear All,
I will really appreciate if any of you can give me solution of my problem which i am facing while doing the lab 1.17 EtherChannel over 802.1q Tunneling from Vol I.
I am exactly following the steps and every thing seems to be normal except the port-channel.
On SW1 my STP for vlan is showing Port-channel in ALT BLK mode :
Po14 Altn BLK 19 128.160 P2p
and when i run the command sh etherchannel summary i am having the following output:
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
14 Po14(SU) PAgP Fa0/13(P) Fa0/14(I) Fa0/15(I)
i am not understanding why port Fa0/14 and 15 is in Stand alone state.
I did tried to shut and no shut the interfaces on both switches but it is not solving my issue.
All other things are seems to be normal and i am able to ping the 155.x.146.x address from R1 and R4 ( which obviously using the Fa0/13)
I will be really grateful if some one can answer my question.
Regards
Atif
