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.
