C6576M OSM GE-WAN Interface Dialog Box Chapter 5 Physical Object Dialog Boxes Note The Delay attribute is an informational parameter used only to communicate the current bandwidth to the higher-level protocols (such as IGRP and EIGRP); you cannot adjust the actual delay of an interface with this command. • Bandwidth-Overwrites default bandwidth in kilobits per second. Note The Bandwidth attribute is an informational parameter used only to communicate the current bandwidth to the higher-level protocols (such as IGRP, EIGRP, and OSPF); you cannot adjust the actual bandwidth of an interface with this command. Layer 2 Area The Layer 2 area of the C6576M OSM GE-WAN interface dialog box provides the following information: • MAC Address-Displays the MAC address of the interface. • MTU-The size, specified in octets, of the largest datagram (frame) that can be sent on the interface. Note A GE interface that is using a nondefault MTU cannot be added to an EtherChannel with GE interfaces using the default MTU. If the interface MTU is changed for one interface, the change is applied to all interfaces (GE and GE EtherChannel) using a nondefault MTU. Note IOS 12.1(8a)E5 caveat: Jumbo frame support is incompatible with the IS-IS routing protocol. Leave the MTU size at the default value on any interface where IS-IS provides routing. Layer 3 Area The Layer 3 area of the C6576M Ethernet Interface dialog box provides the following information: • IP Address-Displays the IP address of the layer 3 interface. • Netmask-Subnet mask of the interface IP address. Enabled bits indicate the network addressing bits in the IP address. • Clear IP Address button-After receiving confirmation, will unset the IP address for this interface. Performance Tab Figure 5-60 shows the Performance tab of the C6576M OSM GE-WAN Interface dialog box. All attributes in this area are read-only. 5-118 Cisco 6500/7600 Series Manager User Guide
