Default IP Gateway Configuration
Alteon can be configured with up to 255 gateways. Gateways 1 to 4 are reserved for default gateway load balancing. Gateways 5 to 259 are used for load-balancing of VLAN-based gateways.
Alteon needs an IP interface for each default gateway to which it is connected. Each interface needs to be placed in the appropriate VLAN. These interfaces are used as the primary and secondary default gateways for Alteon.
This option is disabled by default.
For information about configuring which gateway is selected when multiple default gateways are enabled, see /cfg/l3/metrc <metric name> Default Gateway Metrics.

Default Gateway Options (/cfg/l3/gw) 
Command Syntax and Usage
ipver <IP version (v4 or v6)>
 
Sets the IP version.
addr <default gateway address (such as, 192.4.17.44 for IPv4 or 3001::abcd:1234 for IPv6)>
 
Configures the IP address of the default IP gateway using dotted decimal notation for IPv4 and colon notation for IPv6.
intr <0-60|none>
 
Alteon pings the default gateway to verify that it is available. This command sets the interval, in seconds, between health checks.
If Alteon does not find the default gateway IP address, it assumes the gateway is offline. When this option is set to 0 or none, on initial configuration of the gateway default IP address, neighbor solicitation is sent.
Values:
*0 — For IPv4 and IPv6 addresses only: ICMP health checks are not sent, periodic neighbor solicitation is sent.
*none — For IPv6 addresses: ICMP health checks and periodic neighbor solicitation are not sent. This option is not applicable to IPv4 addresses.
*1 – 120 — The interval between ICMP health checks that Alteon sends to the default gateway.
Default: 2
retry <number of attempts (1-120)>
 
Sets the number of failed health check attempts required before declaring this default gateway inoperative.
Values: 1 – 120 attempts
Default: 8 attempts
vlan <VLAN number (1-4090)>
 
Sets the VLAN to be assigned to this default IP gateway.
prio <high|low>
 
Enables you to change the priority of the default gateway route to either high or low, relative to learned default routes.
*high — The default gateway route is always preferred over learned default routes, such as from the OSPF, BGP, or RIP protocols.
*low — Learned default routes are always preferred over the default gateway route.
Default: low
arp disable|enable
 
Enables or disables Address Resolution Protocol (ARP) health checks.
Default: disable
ena
 
Enables the gateway for use.
dis
 
Disables the gateway.
del
 
Deletes the gateway from the configuration.
cur
 
Displays the current gateway settings.
