Configuration/Packet Rule/Create

To add a new packet rule record to a bridge, click the Create button.

Rule Index and Type

Config Group Index

An index for the packet rule.

For a new packet filter select New.

To group packet filters, select an existing Group Index.

Rule Type

Select the rule you wish to apply to the bridge from the drop-down list. The options for each packet rule packet rule type will appear in the next table.

Packet Rules:

ACL Allow

ACL Deny

Bridge Forbid OUI

Bridge Insert Option82

Bridge Insert PPPoE Vendor Tag

Color Aware Rate Limit Discard

Destination MAC Swap Dynamic

Destination MAC Swap Static

DHCP Relay

DSCP To COS

Filter First Encapsulation VLAN

Filter Second Encapsulation VLAN

Promote First Encapsulation VLAN

Promote Second Encapsulation VLAN

Rate Limit Discard

Rule Value

 

A variable-length field whose meaning depends on the packet rule type.

ACL Allow

  • Rule Value: Rule to allow packets based on source MAC address, destination MAC address, or Ethernet type.

ACL Deny

  • Rule Value: Rule to deny packets based on source MAC address, destination MAC address, or Ethernet type.

Bridge Forbid OUI

  • MAC Address Prefix: specify the first three bytes of the MAC address in order to identify the vendor. These three bytes are called the Organizational Unique Identifier (OUI). This value is stored as a string, but specified in the pattern 'nn:nn:nn...nn:nn', where 'nn' is a hex number specifying a byte of the pattern. E.g. a bridgeConfigValue of '00:02:02'.

Bridge Insert Option82

When acting as a DHCP relay agent, the system includes option 82 to identify the requesting client to the DHCP server.

  • Local ID (can be used as circuit ID)

  • Remote ID (can be used to identify the remote device)

Bridge Insert PPPoE Vendor Tag

  • Optional Tag: Specifies an ASCII string of up to 48 bytes to be inserted into PPPoE discovery packets (PADI/PADR) which transit this node. String will be inserted as a Vendor-Specific tag.

Color Aware Rate Limit Discard

  • Rate (KB/s): The rate limit, CIR, is set in kilobytes per second. For any rate above the set CIR, packets will drop

  • Committed Burst Size (byte):The maximum data rate which can be carried under normal conditions. This rate is greater than the Rate, but less than the EBS.

  • Extended Burst Size (byte): The maximum data rate that the circuit will attempt to carry.

  • COS Green (1-7): CoS values 7-4 are green.

  • COS Yellow (1-7):CoS values 3-0 are yellow.

Destination MAC Swap Dynamic

  • Rule Value: MAC address.

Destination MAC Swap Static

  • Rule Value: MAC address.

  • Static user-specified entry. The SLMS device inserts the user-specified valid  6-byte hexadecimal MAC address into unicast frames not matching the static entry.

DHCP Relay

  • DHCP subnet: Used for DHCP relay. Select a subnet that has been set up for bridged relay in the Configuration / Advanced / DHCP Relay Agent screen.

DSCP To COS

  • Action Index mappings. By default, DSCP are mapped to COS Action Index entries based of RFC 2599.

  • DSCP: COS action index

2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, 17, 18, 20, 22, 24, 25, 26, 28, 30, 32, 33, 34, 36, 38, 40, 42, 43, 44, 45, 46, 48, 50, 51, 52, 53, 54, 55, 56, 58, 59, 60, 61, 62, 63, 64: 0

Filter First Encapsulation VLAN

  • VLAN: VLAN ID (1 to 4094)

  • TPID: Identifies the type of VLAN used. Typically set to 8100.

Filter Second Encapsulation VLAN

  • VLAN: VLAN ID (1 to 4094)

  • TPID: Identifies the type of VLAN used. Typically set to 8100.

  • CoS Value

Promote First Encapsulation VLAN

  • VLAN: VLAN ID (1 to 4094)

  • TPID: Identifies the type of VLAN used. Typically set to 8100.

  • CoS Value

Promote Second Encapsulation VLAN

  • VLAN: VLAN ID (1 to 4094)

  • TPID: Identifies the type of VLAN used. Typically set to 8100.

Rate Limit Discard

  • Rate (KB/s): Color blind rate limiting is usually set when one service is supplied per VLAN. The rate limit, CIR, is set in kilobytes per second. For any rate above the set CIR, packets will drop

  • Committed Burst Size (byte):The maximum data rate which can be carried under normal conditions. This rate is greater than the rate, but less than the EBS.

  • Extended Burst Size (byte): The maximum data rate that the circuit will attempt to carry.
