etherchannel numbering...

the net acad lab wants you to label the three prong switch lab etherchannels as 1,1 2,2 and 2,1...

dls1#config t
Enter configuration commands, one per line.  End with CNTL/Z.
dls1(config)#int rang f0/7 - 8
dls1(config-if-range)#channel-g 1 mode active
Creating a port-channel interface Port-channel 1
dls1(config)#int rang f0/9 - 10
dls1(config-if-range)#channel-g 2 mode active
Creating a port-channel interface Port-channel 2



so dls1 has 2 channels, 1 goes to als1 and 2 goes to als2...
then the channel from als1 to als 2 is set as channel 2 connecting to channel 1...

i don't like it...

als1#sh ether summ                                                             
omitted 
Group  Port-channel  Protocol    Ports                                         
------+-------------+-----------+-----------------------------------------------
1      Po1(SU)         LACP      Fa0/7(Pd)   Fa0/8(P)                          
2      Po2(SU)         LACP      Fa0/11(Pd)  Fa0/12(P)   

als2#sh ether summ
omitted
Group  Port-channel  Protocol    Ports
------+-------------+-----------+-----------------------------------------------
1      Po1(SU)         LACP      Fa0/11(Pd)  Fa0/12(P)  
2      Po2(SU)         LACP      Fa0/9(Pd)   Fa0/10(P)  
 

i prefer the channels connecting to each other with a measure of sanity... als1 to als2 should be 3 to 3

dls1 to als1 channel 1
dls1 to als2 channel 2
als1 to als2 channel 3

so sue me... make the numbers meaningful, not confusing...
