create cpu access_profile
Description
The create cpu access_profile command is used to create an access profile used only for CPU
Interface Filtering. Masks can be entered that will be combined with the values the Switch finds in
the specified frame header fields. Specific values for the rules are entered using the config cpu
access_profile command, below.
ethernet − Specifies that the Switch will examine the layer 2 part of each packet header.
Parameters

ip − Specifies that the switch will examine the IP address in each frame's header.

Example usage:
To create a CPU access profile:
xStack DGS-3400 Series Layer 2 Gigabit Managed Switch CLI Manual
vlan − Specifies that the Switch will examine the VLAN part of each packet header.
source_mac <macmask> - Specifies to examine the source MAC address mask.
destination_mac <macmask> - Specifies to examine the destination MAC address mask.
802.1p - Specifies that the Switch will examine the 802.1p priority value in the frame's
header.
ethernet_type − Specifies that the switch will examine the Ethernet type value in each
frame's header.
vlan − Specifies a VLAN mask.
source_ip_mask <netmask> − Specifies an IP address mask for the source IP address.
destination_ip_mask <netmask> − Specifies an IP address mask for the destination IP
address.
dscp − Specifies that the switch will examine the DiffServ Code Point (DSCP) field in each
frame's header.
icmp − Specifies that the switch will examine the Internet Control Message Protocol (ICMP)
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 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_mask <hex 0x0-0xffffffff> − 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.
