9-20 CHAPTER 9: ADMINISTERING IP ROUTING
Setting the BOOTP
Hop Count Limit
You can set the maximum hop count for a packet to be forwarded through
the router. The range is 0 through 16. The default is 4.
To set the hop count limit:
1 From the top level of the Administration Console, enter:
ip udpHelper hopCountLimit
2 Enter the BOOTP relay hop count limit.
Setting the BOOTP
Relay Threshold
You can set the maximum time limit that a packet is forwarded through the
router. If you use 0 as threshold value, the router ignores the seconds field. If
you use a non zero value, the router uses that value along with the hop
count value to determine whether to forward the UDP packet.
To set the BOOTP relay threshold:
1 From the top level of the Administration Console, enter:
ip udpHelper threshold
2 Enter the BOOTP relay threshold value.
Enabling and
Disabling IP
Routing
You can control whether the system forwards or discards IP packets
addressed to other hosts. When you enable IP routing, the switching
module acts as a normal IP router, forwarding IP packets from one subnet to
another when required. When you disable IP routing, the system discards
any IP packets not addressed directly to one of its defined IP interfaces.
By default, IP routing is disabled on the system.
To enable or disable IP routing:
1 From the top level of the Administration Console, enter:
ip routing
2 Enter the IP routing state (enable or disable).
