Parameters
ip ip-address: Displays the DHCP snooping entries corresponding to the specified IP address.
|: Filters command output by specifying a regular expression. For more information about regular
expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Usage guidelines
Only the DHCP snooping entries containing IP-to-MAC bindings that are present both in the DHCP-ACK
and DHCP-REQUEST messages are displayed by using the display dhcp-snooping command.
Examples
# Display all DHCP snooping entries.
<Sysname> display dhcp-snooping
DHCP Snooping is enabled.
The client binding table for all untrusted ports.

Field Description
Type
Entry type:
• D—Dynamic.
• S—Static. Static DHCP snooping entries are not supported.
• R—Specifies that the DHCP snooping entry is being restored through the
DHCP snooping entry file, and the interface in the entry is invalid.
IP Address IP address assigned to the DHCP client.
MAC Address MAC address of the DHCP client.
Lease Remaining lease duration in seconds.
VLAN
Outer VLAN tag when DHCP snooping and QinQ are both enabled or the
DHCP snooping device receives a packet with two VLAN tags, or VLAN
where the port connecting the DHCP client resides.
SVLAN
Inner VLAN tag when DHCP snooping and QinQ are both enabled or the
DHCP snooping device receives a packet with two VLAN tags, or N/A.
Interface Port to which the DHCP client is connected.
