What is the correct way to create a port channel between an SG300 and Cisco4506 running CatOS
02-26-2018 10:29 PM
interface Port-channel2
description portchannel on sg300
switchport mode trunk
switchport trunk allowed vlan 2,4,6,8,10
!
interface gigabitethernet2
switchport mode trunk
channel-group 2 mode auto
!
interface gigabitethernet3
switchport mode trunk
channel-group 2 mode auto
------------------------
interface Port-channel1
description portchannel on 4506
switchport mode trunk
switchport trunk allowed vlan 2,4,6,8,10
!
interface gigabitethernet 2/1
switchport mode trunk
channel-group 1 mode auto
!
interface gigabitethernet 2/2
switchport mode trunk
channel-group 1 mode auto
If you want to port channel as L3 interface then both member ports are must be L3.

Hi Deepak, the 4506 switch is running CatOS (cat4000-k8.8-4-11-GLX.bin) with1000BaseX Supervisor WS-X4013
i have an active port channel between the 4500 ports and 3560 the configuration is:
CatOS 4506
#port channel set port channel 1/1-2 5 >>>>>>>>>>>>>port channel active set port channel 2/25-28 8 set port channel 3/1-4 14 set port channel 3/45-48 25 set port channel 2/13-16 29 ! #module 1 : 2-port 1000BaseX Supervisor set vlan 10 1/1-2 set port trap 1/1-2 enable set trunk 1/1 on dot1q 1-1005,1025-4094 set trunk 1/2 on dot1q 1-1005,1025-4094 set port channel 1/1-2 mode desirable non-silent ! #module 2 : 48-port 10/100/1000 Ethernet set vlan 30 2/25,2/28,2/41 set vlan 94 2/37,2/48 set vlan 400 2/1-24,2/26-27,2/29-36,2/38-40,2/42,2/46-47 set vlan 962 2/43-45 set trunk 2/28 off dot1q 1-1005,1025-4094 set trunk 2/40 off dot1q 1-1005,1025-4094 set trunk 2/48 on dot1q 1-1005,1025-4094 set spantree portfast 2/28 enable set port channel 2/28 mode off ! #module 3 : 48-port 10/100BaseTx Ethernet set vlan 10 3/1-2 set vlan 30 3/3-4 set vlan 400 3/5,3/7-48 set vlan 900 3/6 set port membership 3/48 dynamic set trunk 3/1 on dot1q 1-1005,1025-4094 set trunk 3/2 on dot1q 1-1005,1025-4094 set trunk 3/48 off dot1q 1-1005,1025-4094 set spantree portfast 3/48 enable set port channel 3/1-2 mode on set port channel 3/48 mode off
3560
interface Port-channel40 switchport trunk encapsulation dot1q switchport trunk native vlan 10 switchport mode trunk ! interface GigabitEthernet0/1 switchport trunk encapsulation dot1q switchport trunk native vlan 10 switchport mode trunk channel-group 40 mode desirable non-silent ! interface GigabitEthernet0/2 switchport trunk encapsulation dot1q switchport trunk native vlan 10 switchport mode trunk channel-group 40 mode desirable non-silent
Now when i try the configure a port channel between 4506 and SG300 failed, i've used on the ports 3/1-2 on the CatOS and this for SG300 but doesn't work.
SG300
interface gigabitethernet27 channel-group 1 mode on ! interface gigabitethernet28 channel-group 1 mode on ! interface Port-channel1 description portchannel-sg300 switchport trunk native vlan 10

As I am getting your point there is some configuration issue.
Please check below link and read about silent or non-silent mode.

Hi,
Contrary to Cat3560 with SG300 you should specify Vlans permitted within a trunk. Will you please add these via the "switchport trunk allowed vlan add" command under the "Interface Port-Channel1". Required Vlans also need to be configured first under the "vlan database".
Best regards,
Antonin
