Switch Feature Overview 65
CDP Interoperability Through ISDP
Industry Standard Discovery Protocol (ISDP) allows the Dell EMC
Networking N-Series switch to interoperate with Cisco devices running the
Cisco Discovery Protocol (CDP). ISDP is a proprietary layer-2 network
protocol which inter-operates with Cisco network equipment and is used to
share information between neighboring devices (routers, bridges, access
servers, and switches).
For information about configuring ISDP settings, see "Discovering Network
Devices" on page 875.
Remote Monitoring (RMON)
RMON is a standard Management Information Base (MIB) that defines
current and historical MAC-layer statistics and control objects, allowing real-
time information to be captured across the entire network.
For information about configuring managing RMON settings, see
"Monitoring Switch Traffic" on page 559.
N3000 Series Access and Aggregation Firmware Images
There are two N3000 switch firmware images available. The Access Router
image runs on both N3000 and N2000 switches. The image file is named
N3000_N2000v
A.B.C.D .stk, where A , B , C , and D are the version numbers.
This image supports all switch capabilities except for BGP. The
D (build
number) in the image file name is enumerated starting with 1. N3000 series
switches are loaded with the Access Router image in the factory.
The Aggregation Router image runs on N3000 model switches and is named
N3000_BGPv
A.B.C.D .stk. The D (build number) in the name is enumerated
starting with 31. The Aggregation Router image supports MP-BGP and all
other switch features except for MLAG, MVR, Auto-VoIP, GARP, GVRP,
GMRP, iSCSI, and DVLAN (QinQ).
Which image type is installed can be determined by examining the first few
lines of the running-config. The following example shows an Aggregation
Router (BGP-enabled) firmware.
