Example
The following shows mirroring configured from port 6 to port 11:
AMAP Configuration
The AMAP protocol discovers adjacent switches by sending and receiving AMAP
“Hello” packets on active Spanning Tree ports. Each port can be defined as being in
one of three logical states of processing the AMAP "Hello" packets:
• Discovery — The initial state where a port transmits a “Hello” packet to detect an
adjacent switch and then waits for a response.
• Common — The port has detected an adjacent switch and periodically sends
“Hello” packets to determine that it is still present.
• Passive — A port enters this state if there is no response to a Discovery “hello”
packet. This is a receive-only state and no “Hello” packets are transmitted. If a
“Hello” packet is received from an adjacent switch, the port enters the Common
state and then transmits a “Hello” packet in reply.
Use the AMAP Global Configuration screen to enable/disable AMAP and configure
timeout parameters.
