Radiance 10/100 Mbps Services Line Card
8
Two versions of the operational software, the FPGA firmware, and
configuration files can be stored on the services line card. New
embedded software can be downloaded easily in the field as upgrades
become available.
The 10/100 Mbps services line card can be managed as an independent
network interface device (NID) with its own IP address. As a NID at the
CPE demarcation point, the services line card responds to SNMP
requests addressed to unicast and subnet broadcast addresses by deliv-
ering information on its health and status as well as its network
connection. SNMP provides Internet-standard management and can be
used for surveillance and fault management.
The versatile R821-1S provides a 10/100BASE-T port (Port 1) and a
small form-factor pluggable (SFP) port (Port 2) with numerous
wavelength and distance options. Typically, Port 1 is designated as the
access port and Port 2 as the network port. To simplify device configu-
ration, a third console port is provided for direct access to the services
line card’s management agent.
Both Ethernet interfaces on the services line card support VLAN double-
tagging, baby giant frames (up to 1532 bytes untagged and 1536 bytes
tagged), and auto-negotiation. When auto-negotiation is enabled, the
copper port auto-detects MDI-II/MDI-X
1
. Both ports also support flow
control (forced collisions in half duplex and PAUSE frames in full duplex).
