Hi All,,
I really need help now guys. I have 8-2960x access switches that is connected to 2-3750x core switches. The uplinks of the 2960x switches will just shutdown unexpectedly even if i just followed the same and old switch configuration.
Here is my Uplink config of 1 of my access switch and core siwtch.
Access switch:
interface Port-channel1
switchport mode trunk
interface GigabitEthernet1/0/50
description "UP-LINK01"
switchport mode trunk
channel-group 1 mode desirable
!
interface GigabitEthernet1/0/52
description "UP-LINK02"
switchport mode trunk
channel-group 1 mode desirable
Core siwtch:
interface Port-channel2
switchport trunk encapsulation dot1q
switchport mode trunk
interface GigabitEthernet2/0/1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 2 mode desirable
!
interface GigabitEthernet2/0/2
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 2 mode desirable
Here is the stat:
#sh interfaces port-channel 1
Port-channel1 is up, line protocol is up (connected)
Hardware is EtherChannel, address is c472.9563.03b4 (bia c472.9563.03b4)
MTU 1500 bytes, BW 2000000 Kbit/sec, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 1000Mb/s, link type is auto, media type is unknown
I have tried setting both channels with duplex full but still shutdowns unexpectedly.
Your advise is much appreciated. I badly need help right now, my boss will be very agree if this issue will not be solved within the week.
Thanks (bow)
