Hitachi GR2000 Series manual Supported L2 UPC functions for each RP type

Filtering/QoS Information

[{-Description:l2upcoff-l2upcContract}]bandwidth monitoring is executed based on the length of from MAC header to FCS of sent and received packets. This parameter is enabled when combined with -upc, -max rate and -min rate. When setting this parameter in RP-A1, RP-C and RP-D, contract bandwidth monitoring is executed based on length excluding the MAC header and FCS of sent and received packets. A list of supported L2 UPC functions for each RP type is indicated in Table 1-7, Supported L2 UPC functions for each RP type.

-l2upc_off:

Bandwidth monitoring is executed based on length excluding the MAC header and FCS of sent and received packets.

-l2upc:

Bandwidth monitoring is executed based on length from the MAC header to FCS of sent and received packets.

Default: -l2upc_off

Range value: None

*1: Only Ethernet V2 format frames are supported. Therefore, errors occur with bandwidth monitoring in 802.3 format frames. In addition, errors also occur with bandwidth monitoring in PPP frames and MPLS frames in Ethernet.

[{-precedenceDescription:mask_offEnables-precedencethe upper_mask}]3 bits of the ToS field of sent and received packets as flow detection conditions. When this parameter is set, only the upper 3 bits (precedence value) of the specified DSCP value are enabled even if the DSCP value of flow detection conditions is set for the device overall.

-precedence_mask_off:

Enables the DSCP value of sent and received packets as flow detection conditions.

-precedence_mask:

Enables the precedence value of sent and received packets as flow detection conditions.

Default: -precedence_mask_off

Range of value: None
