What do the flags in the routing table on a ProxySG indicate?

ProxySG Software - SGOS


With the command, show static-routes entered via the Command Line Interface (in conf t) of a ProxySG Appliance, the results appear as follows:

Destination        Gateway            Flags    Refs      Use      Netif Expire
default        UGS         1     9830        0:0      GS          1        0        0:0


The flags column can be interpreted with the help of the table below:

UUp: The route is active.
HHost: The route destination is a single host.
GGateway: Send anything for this destination on to this remote system, which will figure out from there where to send it.
SStatic: This route was configured manually, not automatically generated by the system.
CClone: Generates a new route based upon this route for machines we connect to. This type of route is normally used for local networks.
WWasCloned: Indicated a route that was auto-configured based upon a local area network (Clone) route.
LLink: Route involves references to Ethernet hardware. 
MIndicates a route that was modified, probably by a dynamic routing protocol running on this system, using the mod option. 
DIndicates that this route was added because of an ICMP Redirect Message. When a system learns of a route via an ICMP Redirect, it adds the route to its routing table so that additional packets bound for that destination will not need to be redirected. The system uses the D flag to mark these routes.
