DESCRIPTION
You can use the general component to modify how the system processes local traffic.

EXAMPLES
modify general maintenance-mode enabled
Places the Local Traffic Manager system in maintenance mode.

list general
Displays the general properties of the local traffic management system.

OPTIONS
gratuitous-arp-rate
Specifies how fast gratuitous ARPs can be sent. If it is 0, then gratuitous ARPs are sent without pause. Otherwise, it
specifies how many gratuitous ARPs can be sent every second. The default value is 0. The range is 0 (zero) to
2147483647."

l2-cache-timeout
Specifies, in seconds, the amount of time that records remain in the Layer 2 forwarding table, when the MAC address of
the record is no longer detected on the network.

The default value is 300 seconds. The range is 0 (zero) to 2147483647 seconds.

maintenance-mode
Specifies, when enabled, that the unit is in maintenance mode. In maintenance mode, the system stops accepting new
connections and slowly finishes off existing connections.

The default value is disabled.

mgmt-auto-lasthop
Specifies, when enabled, that auto-lasthop should be used for incoming traffic to the management port. That means
return traffic will be sent to the MAC address that originated the traffic rather than looked up using the routing and
ARP/NDP tables.

The default value is enabled.

share-single-mac
Specifies the Media Access Control address (MAC address) that the system assigns to a VLAN. The default value is
unique, which indicates that a VLAN uses a unique MAC address from the pool of mac addresses assigned to each hardware
platform. The global value indicates that all of the VLANs on the system use the same MAC address. The vmw-compat
value indicates that the MAC address of a vlan is allocated in a manner compatible with VMware(tm) vSwitch, and
restricts vlans to a single interface, with no trunks allowed. Changing the value of this feature requires a manual
restart of all TMOS daemons.

snat-packet-forward
Enables or disables SNAT packet forwarding. The default value is enabled.
