Operating Notes - HP procurve series 4100gl Management And Configuration Manual

CDP
CDP MIB data is
grouped by type.
That is, the
Address Types
for all detected
CDP devices are
listed first, then
the IP
addresses of the
source devices,
and so on.

Operating Notes

Neighbor Maximum. The Series 4100GL switches support up to 60 entries
(neighbors) in the CDP Neighbors table. Remember that multiple CDP devices
can be neighbors on the same port if they are connected to the switch through
a non-CDP device.
CDP Version Data. The Series 4100GL switches use CDP-V1, but do not
include IP prefix information, which is a router function; not a switch appli-
cation.
Port Trunking with CDP. Where a static or LACP trunk forms the link
between the switch and another CDP device, only one physical link in the
trunk is used to transmit outbound CDP packets.
The first number after the MIB string is the switch port on
which the data point for that entry was received. In this
case, the switch CDP packets on ports A1 and A3. (For CDP
purposes, port numbering is consecutive, from 1 to n,
where n is the last consecutive port on the switch.)
