create cpu access_profile
field in each frame’s header.
• type − Specifies that the Switch will examine each frame’s ICMP Type field.
• code − Specifies that the Switch will examine each frame’s ICMP Code field.
• 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 User 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_mask <hex 0x0-0xff> − Specifies that the Switch will examine each frame’s
Protocol ID field using the hex form entered here.
• 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:
• class – Entering this parameter will instruct the Switch to examine the class field of the IPv6
header. This class field is a part of the packet header that is similar to the Type of Service
(ToS) or Precedence bits field in IPv4.
• flowlabel – Entering this parameter will instruct the Switch to examine the flow label field of
the IPv6 header. This flow label field is used by a source to label sequences of packets
such as non-default quality of service or real time service packets.
• source_ipv6_mask <ipv6mask> - Specifies an IP address mask for the source IPv6
address.
• destination_ipv6_mask <ipv6mask> - Specifies an IP address mask for the destination IPv6
address.
Restrictions Only administrator-level users can issue this command.
