3COM 4500G Port Mirror設定

因學校網路流量有時異常，需要流向監控來查明問題
以下為3COM 4500G Switch設定配置

- Configure GigabitEthernet 1/0/1  as mirroring source ports.

- Configure GigabitEthernet 1/0/15 as the mirroring destination port.

Configuration procedure
Configure Switch C:
# Create a local mirroring group.(一定要設)
================================================================
system-view
<4500G> mirroring-group 1 local

# Configure the source ports and destination port for the local mirroring group.
<4500G> mirroring-group 1 mirroring-port GigabitEthernet 1/0/1
<4500G> mirroring-group 1 monitor-port GigabitEthernet 1/0/15

# Display configuration information about local mirroring group 1.
<4500G>display mirroring-group 1
mirroring-group 1:
    type: local
    status: active
    mirroring port:
        GigabitEthernet1/0/1  both
    monitor port: GigabitEthernet1/0/15
===============================================================


設定完成後較疑惑的是竟然還可以Get DHCP IP，可能3COM把Port Mirror當作HUB功能!?
另外VLAN也全部都撈到了!!
