SIP
SPA interface processor. A SIP is a platform-specific carrier card that inserts into a router slot like a
line card. A SIP can hold one or more SPAs in its subslots, depending on the SIP type. The SPA
provides the network interface. The SIP provides the connection between the Route Processor (RP) and
the SPA.
SNMP
Simple Network Management Protocol. The protocol governing network management and monitoring
of network devices and their functions.
SPA
shared port adapter. A SPA is a modular, platform-independent port adapter that inserts into a subslot
of a compatible SIP carrier card to provide network connectivity and increased interface port density.
The SPA provides the interface between the network and the SIP.
subslot
Slot on a SIP where a SPA is installed. The primary slot is the chassis slot on the where the SIP is
installed.
V
VLAN
Virtual LAN. Group of devices on one or more LANs that are configured (using management software)
so that they can communicate as if they were attached to the same wire, when in fact they are located
on a number of different LAN segments. Because VLANs are based on logical instead of physical
connections, they are extremely flexible. See also LAN.
