etherchannel and spanning-tree

1. Etherchannel

EtherChannel considerations
info http://packetlife.net/blog/2010/jan/18/etherchannel-considerations/

Hi

I was doing a bit of searching on PAgP & LACP and found this, thought it might come in handy for some. I never realised the commands did what is stated below, must have missed this in the book or had one too many wines at that point 

http://www.edgenetworks.nl/etherchannel.html

channel-group [#] mode on (disables PAgP en LACP)

channel-group [#] mode off (disables PAgP en LACP and prevent the ports to form a port-channel)

channel-group [#] mode auto (use PAgP in a passive mode, it will wait until a PAgP packet will be send)

channel-group [#] mode passive (use LACP in a passive mode, it will wait until a PAgP packet will be send)

channel-group [#] mode desirable (use PAgP in an active mode, it will start to send  PAgP packets)

channel-group [#] mode active (use LACP in an active mode, it will start to send  LACP packets)

https://www.jannet.hk/zh-Hant/post/etherchannel-pagp-lacp/#lacp

假設現時有 16 個 Port 在同一個 EtherChannel，由於所有 Port Priority 預設都是 32768，因此系統選擇 Port ID 最小的 8 個 Port 成為 Active Port，其他則成為 Hot Standby。

2. Spanning-tree
