MAC DHCP DNS

The MAC-DHCP-DNS scaffold allows the operator of the rXg to quickly find/search information about the current MAC Entries, DHCP Leases, and DNS Cache Records. It also provides the operator the status of the DHCP Shared Network Stats, and the status of the configured DHCP Pools.

Note: In cluster deployments, a Cluster Node field is displayed in applicable scaffolds to indicate which node the entry belongs to.

MAC Entries

MAC Entries displays information about devices connected to the rXg. The IP field shows the device's IP address. The MAC field displays the hardware MAC address. The Vendor field shows the manufacturer identified from the MAC address OUI. The If field indicates the network interface. The Expires At field shows when the ARP entry will expire. The Interface and VLAN fields link to the corresponding rXg configuration. The IP6 field indicates whether this is an IPv6 entry.

DHCP Leases

DHCP Leases provides the operator with a list of the current DHCP leases assigned to client devices. The Start field shows when the lease was issued. The IP field displays the assigned IP address. The Client Identifier field shows the unique identifier provided by the DHCP client. The Identifier Type field indicates the type of client identifier used. The Resolved Hostname field displays the hostname if it could be resolved.

The Shared Network field shows which DHCP shared network the lease belongs to. The DHCP Pool field indicates the specific pool from which the address was assigned. The Interface and VLAN fields show the network segment. The IP6 field indicates whether this is an IPv6 lease.

The Fixed Host action provides the operator the ability to quickly create a fixed host reservation for the device. It should be noted that any address assigned to a fixed host should fall outside the range of any configured DHCP pool.

DNS Cache Records

The DNS Cache Records scaffold displays the current entries in the rXg DNS cache. The Updated At field shows when the record was last refreshed. The Name field displays the fully qualified domain name. The Root Domain field shows the top-level domain portion. The Record Type field indicates the DNS record type (A, AAAA, CNAME, MX, etc.). The Data field displays the record data (e.g., the resolved IP address). The IP field shows the IP address if applicable. The Expires At field indicates when the cached record will expire. The IP6 field indicates whether this is an IPv6 record.

DHCP Shared Network Stats

DHCP Shared Network Stats displays statistics for each DHCP shared network. The Name field shows the shared network name. The Size field indicates the total number of addresses available in the network. The Active field shows the number of addresses currently leased. The Available field displays the remaining unleased addresses. The Interface and VLAN fields indicate which network segment the shared network serves.

DHCP Pool Stats

DHCP Pool Stats displays statistics for each configured DHCP pool. The DHCP Pool field shows the pool name. The Size field indicates the total number of addresses in the pool. The Active field shows the number of addresses currently leased from the pool. The Available field displays the remaining unleased addresses in the pool.
