Interswitch Protocol Commands
OmniSwitch 6250 CLI Reference Guide November 2009 page 14-5
amap common time
Sets the common phase transmission time interval. In the common transmission state, an active port sends
AMAP Hello packets to determine adjacent switch failures and disconnects. The common transmission
time specifies the number of seconds to wait between each Hello packet transmission.
amap common [time] seconds
Syntax Definitions
seconds Common transmission time value in seconds (1–65535). Do not use
commas in the value.
Defaults
By default, the common transmission time is set to 300 seconds.
Platforms Supported
OmniSwitch 6250
Usage Guidelines
• Use of the time command keyword is optional.
• To avoid synchronization with adjacent switches, the common transmission time is jittered randomly
by plus or minus ten percent. For example, if the default time is used (300 seconds), the jitter is plus or
minus 30 seconds.
• The common transmission time value is only used by ports in the common transmission state.
• If a Hello packet is received from an adjacent switch before the common transmission time has
expired, the switch sends a Hello reply and restarts the common transmission timer.
• A port reverts to the discovery transmission state if a Hello response is not received after the discovery
time interval (see page 14-3) has expired.
Examples
-> amap common 1200
