The accept-source-mac statement configures which MAC source addresses are accepted
on the logical interface. You can specify the MAC address as nn:nn:nn:nn:nn:nn where n
is a decimal digit. To specify more than one address, include multiple mac-address
mac-address options in the accept-source-mac statement.
After an interface filter is configured, there is an accounting entry that is associated with
the MAC address filter. Counters accumulate if there are packets with matching MAC
source addresses. You can use the show interfaces mac-database Junos OS CLI command
to view the address count.

Configuring Flexible VLAN Tagging on PTX Series Packet Transport Switches

Documentation
This topic describes how to configure flexible VLAN tagging on PTX Series Packet
Transport Switches. In addition to VLAN tagging and stacked VLAN tagging, you can
configure a port for flexible tagging. With flexible VLAN tagging, you can configure two
logical interfaces on the same Ethernet port, one with single-tag framing and one with
dual-tag framing.
To configure mixed tagging, include the flexible-vlan-tagging statement at the [edit
interfaces et-fpc/pic/port ] hierarchy level. You must also include the vlan-tags statement
with inner and outer options or the vlan-id statement at the [edit interfaces et-fpc/pic/port
unit logical-unit-number] hierarchy level:
•
[edit interfaces et-fpc/pic/port]
flexible-vlan-tagging;
unit logical-unit-number {
vlan-id number;
}
unit logical-unit-number {
vlan-tags inner tpid.vlan-id outer tpid.vlan-id;
}

Configuring Tag Protocol IDs (TPIDs) on PTX Series Packet Transport Switches
386
This topic describes how to configure the TPIDs expected to be sent or received on a
particular VLAN for PTX Series Packet Transport Switches.
For other types of Juniper Networks Ethernet PICs, you could configure 8 TPIDs per port.
However, the PTX Series Packet Transport Switches use MTIP and TL to classify a specific
TPID and Ethernet type. For MTIP, you can configure a maximum of 8 TPIDs for each
MAC chip.
