seq Assign a sequence number to a deny or permit filter in an extended IP access list while creating the filter. Syntax Parameters seq sequence-number {deny | permit} {ip-protocol-number | icmp | ip | tcp | udp} {source mask | any | host ip-address} {destination mask | any | host ipaddress} [operator [portnumber ]] [ttl operator] [count [byte] | log] [dscp value] [ecn value] [fragments] [monitor [session-ID]] [no-drop] [order] sequence-number Enter a number from 0 to 4294967290. deny Enter the keyword deny to configure a filter to drop packets meeting this condition. permit Enter the keyword permit to configure a filter to forward packets meeting this criteria. ip-protocolnumber Enter a number from 0 to 255 to filter based on the protocol identified in the IP protocol header. icmp Enter the keyword icmp to configure an ICMP access list filter. ip Enter the keyword ip to configure a generic IP access list. The keyword ip specifies that the access list permits all IP protocols. tcp Enter the keyword tcp to configure a TCP access list filter. udp Enter the keyword udp to configure a UDP access list filter. source Enter an IP address in dotted decimal format of the network from which the packet was received. mask (OPTIONAL) Enter a network mask in /prefix format (/x) or A.B.C.D. The mask, when specified in A.B.C.D format, may be either contiguous or non-contiguous. any Enter the keyword any to specify that all routes are subject to the filter. host ip-address Enter the keyword host and then enter the IP address to specify a host IP address or hostname. operator (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.) portnumber (OPTIONAL) Enter the application layer port number. Enter two port numbers if you are using the range logical operand. The range is from 0 to 65535. The following list includes some common TCP port numbers: • 23 = Telnet • 20 and 21 = FTP-DATA and FTP • 25 = SMTP • 169 = SNMP destination ttl operator Enter the IP address of the network or host to which the packets are sent. Enter the keyword ttl to permit or deny a packet based on the time to live value. The range is from 1 to 255. Enter one of the following logical operand: • eq(equal to) - matches packets that contain a ttl value that is equal to the specified ttl value. • neq(not equal to) - matches packets that contain a ttl value that is not equal to the specified ttl value. • gt(greater than) - matches packets that contain a ttl value that is greater than the specified ttl value.
