Spanning Tree Statistics

The Spanning Tree Statistics screen displays the following statistics:
Bridge Identifier — The bridge address of the Ethernet port
Root Bridge — The bridge root address of the Ethernet port
Designated Bridge ID — The designated Spanning Tree bridge ID of this port
Hello Time — The time interval between issuing STP (Spanning Tree Protocol)
configuration messages
Forward Delay — The amount of time in the "learning" and "listening" states;
half the amount of time that must elapse between the time when it is decided
that a port should become part of the Spanning Tree and the time when data
traffic is allowed to be forwarded to and from that port
Maximum Age — The time at which a configuration message is discarded
Port Identifier — The bridge root port of the Ethernet port
Root Path Cost — The bridge root path cost of the Ethernet port
Root Port — The bridge root port of the Ethernet port.
Designated Port ID — The designated Spanning Tree bridge port ID of this port
Br Topology Changed — The topology change state of Spanning Tree for this
port
Br Topology Changed Count — The number of topology changes of Spanning
Tree for this port
Total Forward Transitions — The total number of times this port has
transitioned from the learning state to the forwarding state
Total BridgeUp Time — The total amount of time that this port has been up as
part of the Spanning Tree bridge

IP over ATM Statistics

The IP Over ATM Statistics screen displays the following statistics:
ARP Status
LAN Router—The IP address of the LAN router that passes the IP traffic over the
ATM network.
MAC Addr—The MAC address of the LAN router that passes the IP traffic over
the ATM network.
ATM Router—The IP address of the ATM router that passes the IP traffic over the
ATM network.
LAN Side Statistics
Received IP Packets—The total number of IP packets received on the port.
Forward IP Packets—The total number of IP packets received from the port and
forwarded.
Discarded IP Packets—The total number of IP packets received from the port and
dropped.
RX ARP Request—The total number of ARP request packets received on the port.
RX ARP Reply—The total number of ARP response packets received on the port.
