I'm working on Lab 2 of Volume 1. Here is what I see between Cat1 and Cat3:
Cat3550-1(config-if-range)#do sh run int f0/21
Building configuration...
Current configuration : 207 bytes
!
interface FastEthernet0/21
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,12,40,100,300,567
switchport mode trunk

udld port
channel-group 13 mode on
end
Cat3550-1(config-if-range)#do sh run int f0/22

Cat3560-3(config-if-range)#do sh run int f0/21

Cat3560-3(config-if-range)#do sh run int f0/22

Cat3560-3(config-if-range)#
Configs look the same. However, if I look at Cat1 i see it is err-disable.
Cat3550-1(config-if-range)#do sh int status | in 21
Fa0/21 err-disabled 1 full 100
10/100BaseTX
Cat3550-1(config-if-range)#do sh int status | in 22
Fa0/22 err-disabled 1 full 100
10/100BaseTX
Cat3550-1(config-if-range)#
and the channel shows down:
Cat3550-1(config-if-range)#do sh etherchannel summ
Flags: D - down P - in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator
u - unsuitable for bundling
w - waiting to be aggregated
d - default port
Number of channel-groups in use: 3
Number of aggregators: 3
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
12 Po12(SU) - Fa0/23(P) Fa0/24(P)
13 Po13(SD) - Fa0/21(D) Fa0/22(D)
14 Po14(SU) - Fa0/19(P) Fa0/20(P)
Cat3550-1(config-if-range)#
Over on Cat3 it shows the following:
Cat3560-3(config-if-range)#
Cat3560-3(config-if-range)#do sh int status | in 21
Fa0/21 notconnect 1 full 100
10/100BaseTX
Cat3560-3(config-if-range)#do sh int status | in 22
Fa0/22 notconnect 1 full 100
10/100BaseTX
Cat3560-3(config-if-range)#
Cat3560-3(config-if-range)#do sh etherc summ
Flags: D - down P - in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use f - failed to allocate aggregator
u - unsuitable for bundling
w - waiting to be aggregated
d - default port
Number of channel-groups in use: 3
Number of aggregators: 3
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
13 Po13(SD) - Fa0/21(D) Fa0/22(D)
23 Po23(SU) - Fa0/19(P) Fa0/20(P)
34 Po34(SU) - Fa0/23(P) Fa0/24(P)
Cat3560-3(config-if-range)#
and the interface shows "notconnect"
Cat3560-3(config-if-range)#do sh int f0/21 | in down
FastEthernet0/21 is down, line protocol is down (notconnect)
Cat3560-3(config-if-range)#do sh int f0/22 | in down
FastEthernet0/22 is down, line protocol is down (notconnect)
Cat3560-3(config-if-range)#
In my experience "notconnect" has always been cabling. Is that the case
here or am I missing something? I've been reading the document:

Thanks in advance for any insight.
