9.8.4 E-Series Ethernet Maintenance Screen
Display an E-series Ethernet card in CTC card view and choose the Maintenance tab to display MAC
address and bandwidth information.
9.8.4.1 MAC Table Window
A MAC address is a hardware address that physically identifies a network device. The ONS 15454 MAC
table, also known as the MAC forwarding table, will allow you to see all the MAC addresses attached to
the enabled ports of an E series Ethernet card or an E series Ethernet Group. This includes the MAC
address of the network device attached directly to the port and any MAC addresses on the network linked
to the port. The MAC addresses table lists the MAC addresses stored by the ONS 15454 and the VLAN,
Slot/Port/STS, and circuit that links the ONS 15454 to each MAC address (Figure 9-36).

9.8.4.2 Trunk Utilization Window
The Trunk Utilization screen is similar to the Line Utilization screen, but Trunk Utilization shows the
percentage of circuit bandwidth used rather than the percentage of line bandwidth used. Click the
Maintenance > Ether Bridge > Trunk Utilization tabs to view the screen. Choose a time segment interval
from the Interval menu.
Note The percentage shown is the average of ingress and egress traffic.
