Intel manual Intel Gigabit Ethernet Switch AXXSW1GB User Guide

Any — Matches the protocol to any protocol.

—Protocol ID — Adds user-defined protocols by which packets are matched to the rule. Each protocol has a specific protocol number which is unique. The possible field range is 0-255.

•Flag Set — Displays the TCP flag that can be triggered.

•ICMP Type — Specifies an ICMP message type for filtering ICMP packets.

•ICMP Code —Specifies an ICMP message code for filtering ICMP packets. ICMP packets that are filtered by ICMP message type can also be filtered by the ICMP message code.

•IGMP Type — Displays the IGMP message type. IGMP packets can be filtered by IGMP message type.

•Source IP Address — Matches the source port IP address to which packets are addressed to the ACE.

•Source Mask — Defines the source IP address wildcard mask. Wildcard masks specify which bits are used and which bits are ignored. A wildcard mask of 255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that all the bits are important. For example, if the source IP address 149.36.184.198 and the wildcard mask is 255.36.184.00, the first eight bits of the IP address are ignored, while the last eight bits are used.

•Destination IP Address — Matches the destination IP address to which packets are addressed to the rule.

•Destination Mask —Indicates the destination IP Address wildcard mask. Wildcards are used to mask all or part of a destination IP Address. Masks specify which bits are used and which bits are ignored. A mask of 255.255.255.255 indicates that no bit is important. A wildcard of 00.00.00.00 indicates that all the bits are not important. For example, if the destination IP address is 149.36.184.198 and the wildcard mask is 255.255.255.00, the last three digits in the IP address are checked while the first 3 sets are ignored.

•Source Port — Defines the TCP/UDP source port to which the rule is matched. This field is active only if 800/6-TCP or 800/17-UDP are selected in the Select from List drop-down menu. The possible field range is 0 - 65535.

•Destination Port — Defines the TCP/UDP destination port. This field is active only if 800/6-TCP or 800/17-UDP are selected in the Select from List drop-down menu. The possible field range is 0 - 65535.

•DSCP — Matches the destination port IP address to which packets are addressed to the rule.

•IP - Prec. — Defines the destination IP address wildcard mask. Select either Match DSCP or Match IP Precedence:

—Match DSCP — Matches the packet DSCP value to the rule. Either the DSCP value or the IP Precedence value is used to match packets to ACLs. The possible field range is 0-63.

—Match IP Precedence — Matches the packet IP Precedence value to the rule. Either the DSCP value or the IP Precedence value is used to match packets to ACLs. The possible field range is 0-7.
