What is a unit in Juniper?
Unit is the designation that Junos uses to allow multiple logical interfaces to be configured on a single physical interface. The interface is for physical configurations and unit is used for logical configuration parameters.
What is family inet address?
You use family inet to assign an IPv4 address. You use family inet6 to assign an IPv6 address. An interface can be configured with both an IPv4 and IPv6 address.
How do I find my juniper MTU size?
Check the protocol MPLS MTU: > show interfaces ge-1/0/0 Physical interface: ge-1/0/0, Enabled, Physical link is Up Link-level type: Ethernet, MTU: 1514, MRU: 1522, LAN-PHY mode, Protocol mpls, MTU: 1488, Maximum labels: 3 <– This value is auto-calculated from the physical interface MTU.
What is family Ethernet switching?
I could be wrong, but ‘family ethernet-switching’ is forcing your port to act like a normal switchport. Only one logical unit can be configured on the port and it’s either in trunk or access mode, to which you can make it a member of one or multiple VLANs depending on the port-mode.
What is unit 0 family in Juniper?
Each unit has a number as a unique identifier. The 0 just refers to the first logical interface. It’s good practice (but not required) to keep the unit number in sync with the VLAN id. In that case unit 0 often refers to the untagged interface. family inet refers to the IPv4 address family.
What is family Inet?
family inet —Incorporate port data into the hash key for flow determination. By default, or if you specify only the layer-3 statement, the router uses the following Layer 3 information in the packet header for per-flow load balancing: Source IP address. Destination IP address. Protocol.
What is MPLS MTU?
Maximum transmission unit (MTU) is a well-known parameter in the IP world. It indicates the maximum size of the IP packet that can still be sent on a data link, without fragmenting the packet. Data links in MPLS networks also have a specific MTU, but for labeled packets.
What is fxp0?
Management Ethernet Interface Overview The router’s management Ethernet interface, fxp0 or em0 , is an out-of-band management interface that needs to be configured only if you want to connect to the router through the management port on the front of the router.
