IBM SC30-3681-08 Bgp-subnets new value, Dls-ignore-lfs new value, Ethernet-security new value

CONFIG Commands

bgp-subnets new value

If you want the BGP speaker to advertise subnet routes to its neighbors, set new value to 1. The default is 0.

dls-ignore-lfs new value

When set to 1, DLSw ignores the ªlargest frameº size bits in source-routed frames when setting up a circuit. This avoids circuit setup problems with some older LAN products that do not set these bits correctly. The default is 0.

ethernet-security new value

When set to a non-zero value, zeros the padding that is applied to Ethernet packets whose data portion is less than the physical minimum of 60 bytes. This may be required for security reasons. Default: 0.

ip-default-ttl #_of_packets

The TTL used in packets that are originated by the router. The default is 64.

Note: It is preferable to set this parameter with the set ttl IP con®guration command. (See the ªSetº section of the ªUsing and Con®guring IPº chapter of Protocol Con®guration and Monitoring Reference Volume 1 .) This patch variable remains for compatibility with con®gurations from older releases.

ip-mtu bytes

This parameter limits the IP MTU size to the speci®ed value. When this parameter is set, the IP MTU size on a given network interface is set to the lesser of the ip-mtu value and the largest value that network interface's con®gured frame size can accommodate.

lnm-link-via-tbport new value

Allows LNM to link to a token-ring over an Ethernet transparent bridge (TB) port.

When set to 1, the LNM link is allowed.

When set to 0, the default, the LNM link is not allowed.

more-lines #_of_lines

The number of lines to display on the console when listing the IP routing table, which uses a ªmore pipeº (¦).

mosheap-lowmark new value

This parameter speci®es the percentage of free MOS heap memory, at which the device noti®es the operator that an out-of-memory error is imminent. This noti®cation allows the operator to take action to free up MOS heap memory before the device receives an error and stops.

When the operator receives noti®cation, the operator can recon®gure the router and then reboot, minimizing the outage to the network. Specifying 0 for this parameter suppresses this warning.

Valid Values: 0 to 100

Default Value: 10

ospf-import-rate rate

Number of routes imported per second.

ping-size bytes

The size of the data portion (that is, excluding IP and ICMP headers) of the ICMP PING packet that is sent via the IP>ping command. Default: 56 bytes. (The size of the PING data can also be entered as a parameter of
