• igmp − Specifies that the Switch will examine each frame’s Internet
Group Management Protocol (IGMP) field.
• type − Specifies that the Switch will examine each frame’s
IGMP Type field.
• tcp − Specifies that the Switch will examine each frames Transport
Control Protocol (TCP) field.
• src_port_mask <hex 0x0-0xffff> − Specifies a TCP port mask for
the source port.
• dst_port_mask <hex 0x0-0xffff> − Specifies a TCP port mask for
the destination port.
• flag_mask [ all | {urg | ack | psh | rst | syn | fin}] – Enter the
appropriate flag_mask parameter. All incoming packets have TCP
port numbers contained in them as the forwarding criterion. These
numbers have flag bits associated with them which are parts of a
packet that determine what to do with the packet. The user may
deny packets by denying certain flag bits within the packets. The
user may choose between all, urg (urgent), ack
(acknowledgement), psh (push), rst (reset), syn (synchronize) and
fin (finish).
• udp − Specifies that the switch will examine each frame’s Universal
Datagram Protocol (UDP) field.
• src_port_mask <hex 0x0-0xffff> − Specifies a UDP port mask for
the source port.
• dst_port_mask <hex 0x0-0xffff> − Specifies a UDP port mask for
the destination port.
• protocol_id − Specifies that the switch will examine each frame’s
Protocol ID field.
• user_define_mask <hex 0x0-0xffffffff> − Specifies that the rule
applies to the IP protocol ID and the mask options behind the IP
header.
• packet_content_mask – Specifies that the switch will mask the
packet header beginning with the offset value specified as follows:
• offset_0-15 - Enter a value in hex form to mask the packet from
byte 0 to byte 15.
• offset_16-31 - Enter a value in hex form to mask the packet from
byte 16 to byte 31.
• offset_32-47 - Enter a value in hex form to mask the packet from
byte 32 to byte 47.
• offset_48-63 - Enter a value in hex form to mask the packet from
byte 48 to byte 63.
• offset_64-79 - Enter a value in hex form to mask the packet from
byte 64 to byte 79.
ipv6 – Denotes that IPv6 packets will be examined by the Switch for
forwarding or filtering based on the rules configured in the config
access_profile command for IPv6. IPv6 packets may be identified by the
following:
