Enabling/ Disabling IP Forwarding 7-13
Setting the Hop
Count Limit
You can set the maximum hop count that a packet is forwarded through
the router. The range is 0 through 16. The default is 4.
To set the hop count limit:
1From the top level of the Administration Console, enter:
ip udpHelper hopCountLimit
2Enter the slot of the switching module for which you want to set the hop
count limit.
3Enter 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 zero is used as the value, the seconds field is ignored by the router.
If a non-zero value is used, 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:
1From the top level of the Administration Console, enter:
ip udpHelper threshold
2Enter the slot of the switching module for which you want to set the BOOTP
relay threshold.
3Enter the BOOTP relay threshold.
Enabling/
Disabling IP
Forwarding
You can control whether a switching module forwards or discards IP packets
addressed to other hosts. When you enable IP forwarding, the switching
module acts as a normal IP router, forwarding IP packets from one subnet to
another when required. When you disable IP forwarding, the switching
module discards any IP packets not addressed directly to one of its defined
IP interfaces.
IP forwarding default By default, IP forwarding is enabled on all switching modules.
