HP (Hewlett-Packard) 2824 Switch User Manual


 
Configuring for Network Management Applications
CDP
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.)
CDP MIB data is
grouped by type.
That is, the
Address Types
for all detected
CDP devices are
listed first, then
the IP
addressesof the
source devices,
and so on.

Click on software, then MIBs.
Operating Notes
Neighbor Maximum. The switch supports 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 switch uses CDP-V1, but do not include IP prefix
information, which is a router function; not a switch application.
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.
