Multihost Mode
Using the MSS
5 - 14
In the previous example, the UDP host entry is actually a broadcast IP
address. Data would be sent to all hosts on that particular subnet.
NOTE:
Any changes to the host table don't take effect until the port is
logged out or the MSS is initialized.
To remove an entry from the host table, use the Show Hostlist command
to find out its entry number, and then use the Host Delete command.
Figure 5-17:
Removing Entries from the Host Table
The MSS will preface TCP and UDP sends with a Ping packet to make
sure the remote hosts are alive. If they are alive, the MSS makes the real
connection and passes the data. If any of them aren’t alive, the MSS
doesn’t connect or retry.
If one of the host connections is terminated prematurely, the MSS will
attempt to reconnect at preset intervals. If a UDP connection attempt
receives an ICMP Unavailable message, the MSS will wait ten seconds
before retrying. The waiting period for Telnet and Rlogin is 120 seconds,
and for LAT it is 30 seconds.
If a host’s flow control blocks the MSS from sending, the MSS will not
send any serial data to that host, but it will send the data to the other
hosts in the host list. The MSS consults all hosts each time it has data to
send; it doesn’t remember which hosts wouldn't accept data in the past.
When the MSS serial port is logged out, all host sessions are disconnected
and the port becomes idle. Depending upon the port’s Autostart setting,
it will either wait for serial data (Autostart disabled) or start the
connection again immediately (Autostart enabled).
