DGS-3000 Series Layer 2 Managed Gigabit Switch Web UI Reference Guide
202
PendingRequests
The number of RADIUS Accounting-Request packets sent to this server that have not
yet timed out or received a response. This variable is incremented when an
Accounting-Request is sent and decremented due to receipt of an Accounting-
Response, a timeout or a retransmission.
Timeouts
The number of accounting timeouts to this server. After a timeout the client may retry
to the same server, send to a different server, or give up. A retry to the same server is
counted as a retransmit as well as a timeout. A send to a different server is counted
as an Accounting-Request as well as a timeout.
UnknownTypes
The number of RADIUS packets of unknown type which were received from this
server on the accounting port.
PacketsDropped
The number of RADIUS packets, which were received from this server on the
accounting port and dropped for some other reason.

IP-MAC-Port Binding (IMPB)
The IP network layer uses a four-byte address. The Ethernet link layer uses a six-byte MAC address. Binding these
two address types together allows the transmission of data between the layers. The primary purpose of IP-MAC-
port binding is to restrict the access to a Switch to a number of authorized users. Authorized clients can access a
Switch’s port by either checking the pair of IP-MAC addresses with the pre-configured database or if DHCP
snooping has been enabled in which case the Switch will automatically learn the IP/MAC pairs by snooping
DHCPv4, DHCPv6, and ND packets and saving them to the IMPB white list. If an unauthorized user tries to access
an IP-MAC binding enabled port, the system will block the access by dropping its packet. For the DGS-3000 series
of switches, active and inactive entries use the same database. The maximum number of entries that can be
created is 510 for IPv4 and 255 for IPv6, by which only a maximum of 127 entries can be active at any given time.
The creation of authorized users can be manually configured by CLI or Web. The function is port-based, meaning a
user can enable or disable the function on the individual port.
IMPB Global Settings
Users can enable or disable the Roaming State, Trap/Log state, DHCPv4/DHCPv6 Snoop state, and ND Snoop
state on the Switch. The Trap/Log field will enable and disable the sending of trap/log messages for IP-MAC-port
binding. When enabled, the Switch will send a trap message to the SNMP agent and the Switch log when an ARP
packet is received that doesn’t match the IP-MAC-port binding configuration set on the Switch.
