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
