(urgent),  ack (acknowledgement), psh 

(push), rst (reset), syn (synchronize), fin 

(finish). 

src port mask - Specify a TCP port 

mask for the source port in hex form (hex 

0x0-0xffff), which you wish to filter. 

dest port mask - Specify a TCP port 

mask for the destination port in hex form 

(hex 0x0-0xffff) which you wish to filter. 

Select UDP to use the UDP port number 

contained in an incoming packet as the 

forwarding criterion. Selecting UDP 

requires that you specify a source port 

mask and/or a destination port mask.  

src port mask - Specify a TCP port 

mask for the source port in hex form (hex 

0x0-0xffff). 

dest port mask - Specify a TCP port 

mask for the destination port in hex form 

(hex 0x0-0xffff). 

protocol id - Enter a value defining the 

protocol ID in the packet header to mask. 

Specify the protocol ID mask in hex form 

(hex 0x0-0xffffffff). 

Port 

The user may set the Access Profile 

Table on a per-port basis by entering an 

entry in this field. Entering all will denote 

all ports on the Switch. The port list is 

specified by listing the lowest switch 

number and the beginning port number 

on that switch, separated by a colon. 

Then the highest switch number, and the 

highest port number of the range (also 

separated by a colon) are specified. The 

beginning and end of the port list range 

are separated by a dash. For example, 

1:3 specifies switch number 1, port 3. 2:4 

specifies switch number 2, port 4. 1:3 - 

2:4 specifies all of the ports between 

switch 1, port 3 and switch 2, port 4 

− in 

numerical order.
