Show local-host flags?

Posted on 2004-12-01
Last Modified: 2008-01-09
Does anyone have a list of flags and what they mean for the show local-host command?  Can this be used in trouble shooting?  Any suggestions for troubleshooting besides the logs?


Interface inside: 10953 active, 127301 maximum active, 0 denied
local host: <>,
    TCP connection count/limit = 1/unlimited
    TCP embryonic count = 0
    TCP intercept watermark = unlimited
    UDP connection count/limit = 0/unlimited
    Global XXX.XXX.XXX.242 Local XXX.XXX.XXX.242
    TCP out XX.XX.183.134:40328 in XXX.XXX.XXX.242:25 idle 0:00:34 Bytes 1830 flags UFIOB

    Hi sunnyd24,
    > Interface inside: 10953 active, 127301 maximum active, 0 denied
    Not sure what these mean
    > local host: <>,
    Interface IP address
    >     TCP connection count/limit = 1/unlimited
    1 active TCP connection. No maximum limit defined
    >     TCP embryonic count = 0
    0 'half open' TCP connections. These are connections where a SYN packet has been received but the connection has not yet been fully established.
    >     TCP intercept watermark = unlimited
    No idea.
    >     UDP connection count/limit = 0/unlimited
    0 current UDP connections. No maximum limit defined
    >   AAA:
    No authentication, or authorisatoion listed.
    >   Xlate(s):
    >     Global XXX.XXX.XXX.242 Local XXX.XXX.XXX.242
    Network Address Translation entries
    >   Conn(s):
    >     TCP out XX.XX.183.134:40328 in XXX.XXX.XXX.242:25 idle 0:00:34
    List of current TCP connections.
    > Bytes 1830 flags UFIOB
    I assume you are specifically asking about this line?

    Thanks for the break down!  Yes, I was referring to the last line.  I couldn't find anything about the flags for this command in any documentation.  I assume they mean something and could be used in some manner, but I can't find anything on it.
