www.dell.com | support.dell.com seq e Assign a sequence number to a deny or permit filter in a trace list while creating the filter. Syntax seq sequence-number {deny | permit} {ip-protocol-number | ip | tcp | udp} {source mask | any | host ip-address} {destination mask | any | host ip-address} [operator port [port]] [precedence precedence] [tos tos-value] [count [byte] | log] To delete a filter, use the no seq sequence-number command. Parameters sequence-number deny permit ip-protocol-number ip tcp udp source mask any host ip-address operator port port destination precedence precedence tos tos-value count Enter a number from 0 to 65535. Enter the keyword deny to configure a filter to drop packets meeting this condition. Enter the keyword permit to configure a filter to forward packets meeting this criteria. Enter a number from 0 to 255 to filter based on the protocol identified in the IP protocol header. Enter the keyword ip to configure a generic IP access list. The keyword ip specifies that the access list will permit all IP protocols. Enter the keyword tcp to configure a TCP access list filter. Enter the keyword udp to configure a UDP access list filter. Enter the IP address of the network or host from which the packets were sent. (OPTIONAL) Enter a network mask in /prefix format (/x). Enter the keyword any to specify that all routes are subject to the filter. Enter the keyword host followed by the IP address to specify a host IP address. (OPTIONAL) Enter one of the following logical operands: • eq = equal to • neq = not equal to • gt = greater than • lt = less than • range = inclusive range of ports (you must specify two ports for the port parameter.) (OPTIONAL) Enter the application layer port number. Enter two port numbers if using the range logical operand. Range: 0 to 65535 The following list includes some common TCP port numbers: • 23 = Telnet • 20 and 21 = FTP • 25 = SMTP • 169 = SNMP Enter the IP address of the network or host to which the packets are sent. Enter the keyword precedence followed by a number from 0 to 7 as the precedence value. Enter the keyword tos followed by a number from 0 to 15 as the TOS value. (OPTIONAL) Enter the keyword count to count packets processed by the filter. 1330 | Security
