Network Management and Monitoring Feature Guide for EX9200 Switches To monitor the IEEE 802.3ah protocol, on the CE-facing PE interface, include the statement at the protocol-down [edit protocols oam ethernet link-fault-management hierarchy level: action-profile profile-name event] In configuration mode, go to the [edit protocols oam ethernet link-fault-management hierarchy level.
Network Management and Monitoring Feature Guide for EX9200 Switches Configuring Link Discovery When the IEEE 802.3ah OAM protocol is enabled on a physical interface, the discovery process is automatically triggered. The discovery process permits Ethernet interfaces to discover and monitor the peer on the link if it also supports the IEEE 802.3ah standard.
Network Management and Monitoring Feature Guide for EX9200 Switches Example: Configuring IEEE 802.3ah OAM Support on an Interface on page 21 Ethernet Interfaces Feature Guide for Routing Devices Disabling the Sending of Link Event TLVs You can disable the sending of link event TLVs.

The sFlow technology is a monitoring technology for high-speed switched or routed networks. sFlow monitoring technology randomly samples network packets and sends the samples to a monitoring station. You can configure sFlow technology on a Juniper Networks EX Series Ethernet Switch to continuously monitor traffic at wire speed on all interfaces simultaneously.
Network Management and Monitoring Feature Guide for EX9200 Switches NOTE: sFlow technology on the switches samples only raw packet headers. A raw Ethernet packet is the complete Layer 2 network frame. An sFlow monitoring system consists of an sFlow agent embedded in the switch and a centralized collector.
Network Management and Monitoring Feature Guide for EX9200 Switches Configuring sFlow Technology for Network Monitoring (CLI Procedure) on page 26 Monitoring Interface Status and Traffic Configuring sFlow Technology for Network Monitoring (CLI Procedure) sFlow technology is a network monitoring technology for high-speed switched or routed networks.
Network Management and Monitoring Feature Guide for EX9200 Switches Requirements This example uses the following hardware and software components: One EX Series switch Junos OS Release 9.3 or later for EX Series switches Overview and Topology sFlow technology samples network packets and sends the samples to a monitoring station.
Page 46
Network Management and Monitoring Feature Guide for EX9200 Switches NOTE: We recommend that you configure the same sampling rates on all the ports on a line card. If you configure different sampling rates are different, the lowest value is used for all ports. You could still configure different rates on different line cards.
Configuring Interfaces for Uplink Failure Detection (CLI Procedure) on page 35 Understanding Uplink Failure Detection Uplink failure detection allows Juniper Networks EX Series Ethernet Switches to detect link failure on uplink interfaces and to propagate the failure to the downlink interfaces so that servers connected to those downlink interfaces can switch over to secondary interfaces.
Network Management and Monitoring Feature Guide for EX9200 Switches Figure 2: Uplink Failure Detection Configuration on Switches Switch Switch link-to-monitor Switch 1 Switch 2 link-to-disable Server For uplink failure detection, you specify a group of uplink interfaces to be monitored and downlink interfaces to be brought down when an uplink fails.
Page 52
Network Management and Monitoring Feature Guide for EX9200 Switches NOTE: After you have configured a group, use the show uplink-failure-detection group group-name command to verify that all interfaces in the group are up. Related Verifying That Uplink Failure Detection Is Working Correctly...
