Symmetrical traffic after update interface

Machi Ma — Tue, 12 Mar 2019 08:04:10 GMT

Hello

Previously I have adjusted the interface from

-------- original version -----
interface GigabitEthernet0/2
speed 1000
duplex full
nameif outside
security-level 0
ip address 111.222.333.2 255.255.255.248
!

interface Port-channel1
duplex full
lacp max-bundle 8
nameif INSIDE
security-level 100
ip address 192.168.0.1 255.255.255.0
!

interface Port-channel1.100
vlan 100
nameif net100
security-level 100
ip address 202.73.1.1 255.255.255.0
!

with policy allocated
Server located at 202.73.1.1/24 is able to access in/out to the internet.

after that, I updated the interface to following. It move 192.168.0.1 to Vlan1 to Vlan 50

----- updated version -------
interface GigabitEthernet0/2
speed 1000
duplex full
nameif outside
security-level 0
ip address 111.222.333.2 255.255.255.248
!

interface Port-channel1
duplex full
lacp max-bundle 8
nameif INSIDE2
security-level 100
ip address 192.168.85.1 255.255.255.0
!

interface Port-channel1.50
vlan 50
nameif INSIDE
security-level 100
ip address 192.168.0.1 255.255.255.0
!
interface Port-channel1.100
vlan 100
nameif net100
security-level 100
ip address 202.73.1.1 255.255.255.0
!
--------------------------------
However, after change. It detected the huge size of symmetrical traffic to 202.73.1.0/24 appear at interface GigabitEthernet0/2.

Could you please advise where I can trace the problem?

Thanks!

Is the problem outgoing, in which case check out "port-channel load-balance", or inbound (in which case, check out whatever it is plugged into).
