Hardware
Extended cable manager for EX9214 switchesAn extended cable manager is now
available for EX9214 switches. The extended cable manager enables you to route
cables away from the front of the line cards and Switch Fabric modules and provides
easier access to the switch than the standard cable manager. To obtain the extended
cable manager, order the MX960 Enhanced Cable Manager, ECM-MX960.(Installation
of the extended cable manager must be done by a technician authorized by Juniper
Networks and that the service cost is in addition to the component cost.)
[See MX960 Cable Manager Description.]
Infrastructure
Support for IPv6 for TACACS+ authentication (EX9200)—Starting with Release 13.3,
Junos OS supports IPv6 along with the existing IPv4 support for user authentication
using TACACS+ servers.
Multicast
MLD snooping on EX9200 switches—Starting with Junos OS Release 13.3, EX9200
switches support Multicast Listener Discovery (MLD) snooping. MLD snooping constrains
the flooding of IPv6 multicast traffic on VLANs on a switch. When MLD snooping is
enabled on a VLAN, the switch examines MLD messages between hosts and multicast
routers and learns which hosts are interested in receiving traffic for a multicast group.
Based on what it learns, the switch then forwards multicast traffic only to those
interfaces in the VLAN that are connected to interested receivers instead of flooding
the traffic to all interfaces. You configure MLD snooping at either the [edit protocols]
hierarchy level or the [edit routing-instancesrouting-instance-name protocols] hierarchy
level.

Network Management and Monitoring
sFlow technology on EX9200 switches—Starting with Junos OS Release 13.3, EX9200
switches support sFlow technology, a monitoring technology for high-speed switched
or routed networks. The sFlow monitoring technology randomly samples network
packets and sends the samples to a monitoring station. You can configure sFlow
technology on an EX9200 switch to continuously monitor traffic at wire speed on all
interfaces simultaneously. The sFlow technology is configured at the [edit protocols
sflow] hierarchy level.
[See Understanding How to Use sFlow Technology for Network Monitoring on an EX Series
Switch.]
