●
Transfer interval: A time interval, in seconds, after which the CDRs are pushed to the
configured IP periodically. All the files that are completed before the PUSH timer
expires are pushed.

DHCP Service Support with MPLS Labels
This support added to configure traffic from the specified DHCP service bind address to use
the MPLS labels. This support also provides the configuration to define the next-hop
gateway address.
the MPLS labels. This support also provides the configuration to define the next-hop
gateway address.
To configure and manage this feature, a new optional keyword
nexthop-forwarding-address nexthop_ip_address
with other options has been added
to the
bind address ip_address
command in DHCP Configuration mode in the
Command Line Interface Reference.
Configuration of this support is explained in Multi Protocol Label Switching chapter in the
System Enhanced Feature Configuration Guide.

Four-Port Gigabit Ethernet Line Card (QGLC)
A new four port Gigabit Ethernet line card (usually referred to as the Quad Gig-E Line Card
or QGLC) has been introduced for the ST40 platform only.
or QGLC) has been introduced for the ST40 platform only.
Using hot-swappable small form-factor pluggable (SFP) modules, the card can support
either 1000Base-SX, 1000base-LX and 1000Base-T configurations. Note that all four ports
must be of one type; there can be no mix-and-matching interfaces.

must be of one type; there can be no mix-and-matching interfaces.
QGLCs can be installed in chassis slots 17 through 23, 26 through 39, and 42 through 48.
These cards should always be installed directly behind their respective PSCs, but are not
required to be placed behind any redundant PSCs (those operating in Standby mode). Cards
inserted in pairs behind an active PSC offer 1:1 redundancy and automatic failover.

It has four ports instead of one which is less expensive than having to buy more than one
line card if you need more than one port. With more ports the QGLC line card increases
aggregate throughput to external devices (up to 2.8 Gbps depending on call model).

The QGLC uses a new generation of Fixed Programmable Gate Array (FPGA).The new
FPGA allows the Star Channel (the 140Gbps internal bus) to be used for firmware upgrades.
This dramatically improves the time it takes upgrade the card firmware for future
enhancements.
