Port-Channel Probleme

[sebastian.f 10]

Hallo

 

Habe ein kleines Problem mit einem PortChannel und einem Server.

Wenn ich den Server neu starte baut sich der Port Channel nicht wieder korrekt auf.

D.h. ich kann den Server nicht mehr erreichen. Erst wenn ich am switch das PortChannel Interface deaktiviere und wieder aktiviere funktioniert der Channel wieder.

Der Server ist ein W2k3 von Compaq (Proliant DL580) mit 2 HP NC7131 Gigabit Karten.

 

Switch: Catalyst 4506 mit Sup 2+ und IOS: 12.1(19)EW1

Port-Channel Config:

!

interface Port-channel1

description PortChannel le1001

switchport

switchport access vlan 2

switchport mode access

!

interface GigabitEthernet3/15

description PortChannel xxxx

switchport access vlan 2

switchport mode access

spanning-tree portfast

channel-group 1 mode active

!

!

interface GigabitEthernet3/42

description PortChannel le1001

switchport access vlan 2

switchport mode access

spanning-tree portfast

channel-group 1 mode active

!

Hat jemand eine Idee warum das erst nach restart des Interfaces wieder funktioniert? Ich habe irgendwie das Gefühl das es am Server und nicht am Switch liegt ...
