DHCP

Supports the following DHCP features:

• DHCPv4 and DHCPv6 client

• DHCPv4 and DHCPv6 server

• DHCPv4 and DHCPv6 relay agent

[See DHCP User Guide.]

• Support for EVPN-VXLAN group-based policies.

  [See Micro and Macro Segmentation using Group Based Policy in a VXLAN.]

• Supports Layer 2 VXLAN gateway services in an EVPN-VXLAN network.

  [See EVPN User Guide.]

  [See EVPN User Guide.]

  The Virtual Chassis doesn’t support EVPN-VXLAN multihoming. You can use the standalone switch as an EVPN-VXLAN provider edge (PE) device in multihoming use cases. We support the following Layer 2 VXLAN gateway features in an EVPN-VXLAN network:

  • Active/active multihoming

  • Proxy ARP use and ARP suppression, and Neighbor Discovery Protocol (NDP) use and NDP suppression on non-IRB interfaces

  • Ingress node replication for broadcast, unknown unicast, and multicast (BUM) traffic forwarding

  [See EVPN User Guide.]

Hardware

• The EX4100-H-12T has the following port configuration:

  • Twelve 1 Gigabit-Ethernet (GbE) non-PoE BASE-T ports

  • Two 1/10 Gbps SFP/SFP+ MACsec-enabled uplink ports

  • Two 1/10 Gbps SFP/SFP+ VCPs. MACsec supported in Network mode.

[See EX4100-H-12T Hardware Guide.]

High availability and resiliency

• Resiliency support for inter-integrated circuit (I2C), disk failure, and disk health.

  [See High Availability User Guide.]

Layer 2 features

• Support for Layer 2 features.

  [See Configuring Q-in-Q Tunneling and VLAN Q-in-Q Tunneling and VLAN Translation, Layer 2 Bridge Domains Overview, and Understanding Layer 2 Learning and Forwarding.]

• Support for Layer 2 multicast features.

  • Local and remote port mirroring, and remote port mirroring to an IP address (GRE encapsulation). [See Port Mirroring and Analyzers.]

Software installation and upgrade

• Support for the PHC.

  Obtaining Configurations and Software Image Without User Intervention Using Phone-Home Client

• Secure boot and common BIOS support (EX4100-H-12T). The Secure Boot implementation is based on the UEFI 2.4 standard. The BIOS has been hardened and serves as a core root of trust. The BIOS updates, the bootloader, and the kernel are cryptographically protected. Secure boot is enabled by default on supported platforms.

  [See Junos OS Overview.]

Timing

• Support for Precision Time Protocol (PTP) transparent clock.

  [See PTP Transparent Clocks.]

Uplink failure detection

• Support for debounce interval configuration. You can configure the debounce interval, which is the time (in seconds) that elapses before the downlink interfaces are brought up after a state change of the uplink interfaces.

  [See Uplink Failure Detection.]

Virtual Chassis

• Support for Virtual Chassis.
