IP Precedence From the IP Precedence section, you can map IP Precedence values to traffic class values. These settings apply to all ports on the switch. The following options are available: l IP Precedence Priority Table — Displays a list of IP Precedence values with mapped CoS values. l Class of Service Value — Maps a CoS value to an IP Precedence value. The number 0 represents low priority and 7 represents high priority.
The DSCP value is six bits wide, allowing coding for up to 64 different forwarding behaviors. The DSCP value replaces the ToS bits, and it retains backward compatibility with the three precedence bits so that non-DSCP compliant, ToS-enabled devices, will not conflict with the DSCP mapping. Based on network policies, different kinds of traffic can be marked for different kinds of forwarding. In the IP DSCP Priority section, you can map DSCP values to traffic class values.
Command Usage map ip precedence Enables IP precedence mapping (IP ToS) for the switch map ip precedence ip-precedence-value cos cos-value Sets IP precedence priority (IP ToS priority) for a port or trunk interface (applies to all ports) show map ip precedence [interface] Shows the IP precedence priority map map ip dscp Enables IP DSCP mapping for the switch map ip dscp dscp-value cos cos-value Sets IP DSCP priority for a port or trunk interface (applies to all ports) show map ip dscp [interface]

ID 1). VLAN ID Name Port Members (Tagged/Untagged) 2 Admin 1 (U), 2 (U), 10 (U) 5 Internal 1 (U), 4 (U), 5 (U) 10 Web 1 (T), 9 (T), 10 (T), 11 (U), 12 (U) 15 Collocation 1 (U), 2 (U), 12 (U) 2.
The specific ports shown in the previous figure have the following PVID settings. The PVID settings for each port are configured in the Port Settings page. Port 01: 2 Port 05: 5 Port 09: 1 Port 02: 2 Port 06: 1 Port 10: 2 Port 03: 1 Port 07: 1 Port 11: 10 Port 04: 5 Port 08: 1 Port 12: 15 The PVID of a port must be set to a VLAN ID of which the port is an untagged member. NOTE: Port 9 cannot be removed from VLAN 1 because its PVID is set to VLAN 1. 3.

If you have a problem that is not listed here and you cannot solve it, contact Dell (see "Getting Help"). LEDs l All light-emitting diode (LEDs) are off.
l ¡ Your management station has management VLAN access (see "Management VLAN Access"). ¡ The switch is powered up. ¡ You have a valid network connection to the switch and the port you are using has not been disabled. Simple Network Management Protocol (SNMP) management software cannot access the switch. Ensure that: ¡ You have configured the switch's management VLAN with a valid IP address, subnet mask, and default gateway.
In the preceding figure, the management VLAN is different on each switch, with the Layer 3 switch interconnecting the VLANs. The ports that interconnect the switches are configured as tagged ports. The ports on the Layer 3 switch that connect to the other switches must be configured as members of the management VLAN for each switch. For management VLAN access, ensure that: l You have configured the switch's management VLAN with a valid IP address, subnet mask, and default gateway.
