Quality of Service Overview Figure 17-1 Is propagated through the network in the protocol packet header Assigning and Marking Traffic with a Priority The ICMP protocol, used for error messaging, has a low bandwidth requirement, with a high tolerance for delay and jitter, and is appropriate for a low priority setting. For information on the command syntax and parameters, refer to the online help or the CLL Reference for your platform. RIP is described in RFC 2453. While Enterasys Discovery Protocol and Cisco Discovery Protocol are vendor-specific protocols, LLDP is an industry standard (IEEE 802.1AB), vendor-neutral protocol. . See Table 11-2 on page 11-7 for a description of port parameters. @ # $ % ^ & * () ? Implementing VLANs building has its own internal network. Use the passive-interface command in router configuration command mode to configure an interface as passive or to set passive as the default mode of operation for all interfaces. VRRP is available only on those fixed switch platforms that support advanced routing and on which an advanced feature license has been enabled. If Router R1 should become unavailable, Router R2 would take over virtual router VRID 1 and its associated IP addresses. The following example configures DHCP snooping and dynamic ARP inspection in a routing environment using RIP. First, the module is verified as present in Slot 2, and the port status is shown as operating as a 1000BASE-SX port. Display the MAC addresses in the switchs filtering database (FID). The following port administrative states are set by default: lacpactive - Transmitting LACP PDUs is enabled.

Quality of Service Overview Additional port groups, up to eight (0 through 7) total, may be created by changing the port group value. When a root or alternate port loses its path to the root bridge, due to message age expiration, it takes on the role of designated port and will not forward traffic until a BPDU is received. OSPFv2 is available only on those fixed switch platforms that support advanced routing and on which an advanced feature license has been enabled. Packet flow sampling will cause a steady, but random, stream of sFlow datagrams to be sent to the sFlow Collector. If you need to use multiple license keys on members of a stack, use the optional unit number parameter with the set license command. The order in which servers are queried is based on a precedence value optionally specified when you configure the server. Tabl e 2510providesanexplanationofthecommandoutput. Neighbor virtual link routers must have the same password. (Not applicable for super user accounts.)
