Jeff,

	802.3ad is LACP not PAGP.

Subject: [c-nsp] PAgP w/Intel PRO issue

Trying to bring up PAgP between a Cat2950 and a Dell 1850, Intel PRO NICs,
Windows 2003 server.  I suspect this may be a "Window-ish" or "Intel-ish"
problem, but would prefer the wisdom of this forum as opposed to theirs :-)

I created the NIC "team" on the server using the PROset utility as an
"802.3ad Dynamic Link Aggregation" pair.

The 2950 is setup for PAgP between ports f0/7-8:

> interface Port-channel1
>  description Raven PAgP channel
>  switchport access vlan 33
>  switchport mode access
>  no ip address

> interface FastEthernet0/7
>  switchport access vlan 33
>  no ip address
>  channel-group 1 mode desirable
>  channel-protocol pagp
>  spanning-tree portfast

> interface FastEthernet0/8
>  switchport access vlan 33
>  no ip address
>  channel-group 1 mode desirable
>  channel-protocol pagp
>  spanning-tree portfast

It doesn't appear to be aggregating.  The Windows side shows the interfaces
up, but the 2nd NIC as "standby" (?).

The 2950 never shows the channel up.
