DHCP Snooping➧
Overview
Starting with version 0.31 WildcoreDMS shows the DHCP Snooping binding table from switches and OLTs: which IP address was issued to which subscriber MAC address, in which VLAN, on which port/ONU and how long the lease remains. This helps quickly find a subscriber by IP or check whether their equipment gets an address.
Where to view➧
| Place | What is shown |
|---|---|
| Switch page → DHCP Snooping tab | All bindings of the device |
| OLT page → DHCP Snooping tab | All OLT bindings matched to specific ONUs |
| Switch port page → DHCP Snooping card | Bindings on this port |
| ONU page → DHCP Snooping card | Bindings behind this ONU |
The tab and cards are shown only for models that support this feature.
The table contains the Interface (port or ONU — linked to its page), MAC address, IP, VLAN ID and remaining lease time. Columns can be filtered and sorted. The refresh button on the tab requests fresh data from the hardware.
ONU card➧
On the ONU page data is requested with the "Get info" button (or "Refresh info" if data is already there): on some models bindings are matched to ONUs through the FDB table, which may take a few seconds.
To load the table automatically together with the rest of ONU information, enable the
load_snooping_info parameter for the
device or model.
Tip
You can hide the card for yourself in Account settings → Interface cards visibility.
