24 Interfaces The commands in this chapter are supported by Dell Force10 operating software (FTOS) on the E-Series, C-Series, SSeries, S4810, or Z-Series platforms. Although all interfaces are supported on E-Series ExaScale, some interface functionality is supported on E-Series ExaScale with FTOS 8.2.1.0 and later. When this is the case, it is noted in the Command History section. This chapter contains the following sections: • Basic Interface Commands • Port Channel Commands • Time Domain Reflectometer (TDR) • UDP Broadcast Basic Interface Commands The following commands are for Physical, Loopback, and Null interfaces. clear counters Clear the counters used in the show interfaces commands for all virtual router redundancy protocol (VRRP) groups, virtual local area networks (VLANs), and physical interfaces, or selected ones.

For the C-Series and SSeries, the range is 1 to 128. For the E-Series, 1 to 255 for TeraScale and 1 to 512 for ExaScale. • For the management interface on the RPM, enter the keyword ManagementEthernet followed by slot/port information. The slot range is 0 to 1 and the port range is 0. • For a SONET interface, enter the keyword sonet followed by the slot/port information. 757
