Switch "X"
CDP Enabled on Port A1
CDP Neighbor Table
Port | Data
------|------------------
A1 | 10.28.227.103
Thus, CDP switch "X" detects CDP switch "Y" on port A1 and shows 10.28.227.103 in its CDP table entry because in CDP switch "Y" the
Primary VLAN does not have an IP address and the Blue_VLAN has a lower VID than the Red_VLAN.

Addresses

CDP Neighbor Data and MIB Objects

The switch places the data received from inbound CDP packets into its MIB
(Management Information Base). This data is available in three ways:
I
I
I
As shown under "Viewing the Current Contents of the Switch's CDP Neighbors
Table" on page 12-19, you can list a subset of data for each CDP device
currently found in the switch's CDP Neighbors table. Table 12-2, "CDP
Neighbors Data", describes the CDP Neighbor data set available in the Switch
4108GL.
