Interface Configuration Guide 7705 SAR Interfaces
Edition: 01 3HE 11011 AAAC TQZZA 31
The ports and features on the 6-port Ethernet 10Gbps Adapter card are identical to
the ports and features on the 8-port Gigabit Ethernet Adapter card, version 3, except
that the 6-port Ethernet 10Gbps Adapter card uses only 4-priority schedulers for QoS
instead of 4-priority or 16-priority schedulers.
3.1.3.1.2 8-port Ethernet Adapter Card
The 8-port Ethernet Adapter card (the 7705 SAR-18 only supports version 2) has six
RJ-45 ports for 10/100Base-T (Ethernet and Fast Ethernet) connections. The card
also has two SFP ports for fiber or copper SFPs. Fast Ethernet and Gigabit (100 Mb/s
and 1000 Mb/s) fiber connections and 10/100/1000Base-T copper connections are
supported. This variety of connections enables the 8-port Ethernet Adapter card to
be connected to different devices at the customer site, including wireless base
stations, DSL modems, microwave boxes, and other auxiliary equipment. As well,
with fiber connections, the adapter card can be directly connected to the Metro
Ethernet Provider (MEP) central office. Version 2 of the 8-port Ethernet Adapter card
also supports synchronous Ethernet timing.
3.1.3.1.3 8-port Gigabit Ethernet Adapter Card
The 8-port Gigabit Ethernet Adapter card has eight SFP ports for fiber or copper
SFPs. The card supports dual rate (100 Mb/s and 1000 Mb/s) and Gigabit (1000
Mb/s) fiber connections and 10/100/1000Base-T copper connections. The card also
supports synchronous Ethernet timing. The 8-port Gigabit Ethernet Adapter card is
designed to complement or replace the 8-port Ethernet Adapter card in situations
where greater processing power and higher throughput capacity are required.
There are three versions of the 8-port Gigabit Ethernet Adapter card. Version 1 and
version 2 are identical except that version 2 provides larger table space for FIBs,
ACLs, and so on. Version 2 also supports the full IPv6 subnet range for IPv6 static
routes and interface IP addresses. The static route range is from /1 to /128, and the
default route is ::/0. Supported interface IP address prefixes are from /4 to /127, and
/128 on system or loopback interfaces. Version 3 is identical to version 2 except that
it is equipped with a hardware-based encryption engine to support features such as
IPSec.
Higher limits and full subnet ranges are supported only when all the adapter cards in
a particular node are equipped with hardware for larger table support.
