One router in the VRRP group will be the. The Juniper Networks EX4300 line of Ethernet switch with Virtual Chassis technology combines the carrier-class reliability of modular systems with the economics and flexibility of stackable platforms, delivering a high-performance, scalable solution for data center.

Junipers Virtual Chassis technology enables up to 10 EX4300 switches to be connected via a 320 Gbps backplane with four 40 GbE ports on the rear panel. B-EX430048P-5M2-E Juniper Networks EX Series EX4300-48P switch 48 ports managed rack mountable. OSPF, IS-IS, RIP-1, RIP-2, BGP, IGMPv2, IGMP, VRRP, PIM-SM, PIM-DM, IGMPv3, OSPFv3, PIM-SSM, statisches IPv4-Routing, statisches IPv6-Routing, RIPng, MPLS, Bidirectional Forwarding Detection (BFD), VRRPv3, CIDR Essentially VRRP describes an election protocol to maintain ownership of this virtual IP (VIP) address and MAC address. The EX4300 Ethernet switches are compact, fixed-configuration platforms that meet the needs of a variety of high-performance branch office, campus, and data center access deployments. MAC limiting protects against flooding of the Ethernet switching table, and is enabled on Layer 2 interfaces (ports). You can now increase the maximum number of searchable hash indexes in increments of 4, from 4 to a maximum of 32 entries, using the CLI command "set ethernet-switching-options mac-lookup-length".Switching-Kapazität: 960 Gbit/s ¦ Durchsatz: 714 Mpps ” For EX3200, EX4200, EX4500, EX4550, EX6200 and EX8200 Series switches, hash index collisions were causing problems with the learning of MAC addresses in the forwarding database (FDB). MAC address table uses a hash-based scheme to program entries therefore. You should consider this may be hash index collision problem that has been reported by Juniper as PR842439. The highly flexible, high-performance Juniper Networks QFX5100 line of.

In case you are encoutering the problem thatġ, eth port of the host failed to work, and that host is connecting to a switch trunk port via hub/vmware platform,ģ, switch port has learned massive mac address from that port, and a lot of learned mac addresses from different vlans are exactly identical This is due to hash index collision that can be fixed by changing the value Some of mac address may failed to be learned by the port. Juniper EX switche has one port configured as trunked ports, when there are too many mac address learned from that port,
