Field Description Field Name
Encapsulation type:
■
AAL0—VCC cell relay–encapsulated circuits that receive raw
ATM cells
■
AAL5—ATM cross-connect interfaces
Encap
Maximum number of ATM cells that the router can concatenate in
a single packet; if this value is not configured, “ Martini cell
aggregation: disabled” appears instead of this field. Displayed for
an individual ATM over MPLS interface with AAL0 encapsulation Maximum number of cells
per packet
Identifier (1, 2, or 3) of the ATM Martini cell packing timer that
detects timeout of the cell collection threshold; if this value is not
configured, “ Martini cell aggregation: disabled” appears instead
of this field. Displayed for an individual ATM over MPLS interface
