CAR port table

The Common Access Rate (CAR) port table shows the definitions of CAR objects.

Description

snPortCARTable

1.3.6.1.4.1.1991.1.1.3.16.1.1

None

The CAR port table.

snPortCARifIndex

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.1

Syntax: Integer

Read-only

Shows the ifIndex value for this rate limit entry.

snPortCARDirection

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.2

Syntax: Integer

Read-only

Specifies the transmission direction of the rate-limit object:

  • input(0) - For inbound traffic.
  • output(1) - For outbound traffic.
snPortCARRowIndex

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.3

Syntax: Integer

Read-only

Shows the table index for rate limit objects. Rows are numbered in sequential order. When a row is added, it is assigned the next sequential number. When a row is deleted, the row is skipped.

snPortCARType

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.4

Syntax: RateLimitType

Read-only

Shows the type of traffic to which the rate limit is applied:

  • standardAcc(1) - Traffic matches standard access list.
  • quickAcc(2) - Traffic matches the rate-limit access list.
  • all(3) - All traffic.
snPortCARAccIdx

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.5

Syntax: Integer32

Read-only

Indicates the index to the access list if the rate limit type is one of the following:

  • standardAcc(1) - Traffic matches standard access list.
  • quickAcc(2) - Traffic matches the rate-limit access list.
snPortCARRate

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.6

Syntax: Integer32

Read-write

Shows the committed access rate for the long-term average transmission rate in bits per second. Traffic that falls under this rate always conforms to this rate.

snPortCARLimit

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.7

Syntax: Integer32

Read-write

Shows the normal burst size in bytes. Normal burst size is the number of bytes that are guaranteed to be transported by the network at the average rate under normal conditions during the committed time interval.

snPortCARExtLimit

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.8

Syntax: Integer32

Read-only

Shows the extended burst limit in bytes. The extended burst limit determines how large traffic bursts can be before all the traffic exceeds the rate limit.

snPortCARConformAction

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.9

Syntax: Integer

Read-only

Indicates what happens to packets when the traffic is within the rate limit:

  • continue(1) - Continue to evaluate the subsequent rate limits.
  • drop(2) - Drop the packet.
  • precedCont(3) - Rewrite the IP precedence and allow it after evaluated by subsequent rate limits.
  • precedXmit(4) - Rewrite the IP precedence and transmit the packet.
  • xmit(5) - Transmit the packet.
snPortCARExceedAction

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.10

Syntax: Integer

Read-only

Indicates what happens to packets when the traffic exceeds the rate limit:

  • continue(1) - Continue to evaluate the subsequent rate limits.
  • drop(2) - Drop the packet.
  • precedCont(3) - Rewrite the IP precedence and allow it after evaluated by subsequent rate limits.
  • precedXmit(4) - Rewrite the IP precedence and transmit the packet.
  • xmit(5) - Transmit the packet.
snPortCARStatSwitchedPkts

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.11

Syntax: Counter64

Read-only

Indicates the number of packets permitted by this rate limit.

snPortCARStatSwitchedBytes

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.12

Syntax: Counter64

Read-only

Indicates the number of bytes permitted by this interface.

snPortCARStatFilteredPkts

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.13

Syntax: Counter64

Read-only

Indicates the number of packets that exceeded this rate limit.

snPortCARStatFilteredBytes

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.14

Syntax: Counter64

Read-only

Indicates the number of bytes that exceeded this rate limit.

snPortCARStatCurBurst

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.15

Syntax: Gauge32

Read-only

Shows the current burst size of received packets.

snPortCARRowStatus

1.3.6.1.4.1.1991.1.1.3.16.1.1.1.16

Syntax: RowStatus

Read-create The variable is used to create new row in the rate limit table. The supported values are CreateAndGo(4) and destroy(6).
