What is difference between Subinterface and VLAN?
The major difference is that an SVI is bound to a VLAN used for L2 switching, while a subinterface is part of an L3 interface that doesn’t take part in L2 switching. Accordingly, a specific VLAN ID on a subinterface may indicate a different VLAN (L2 segment aka broadcast domain) than the same VLID on another interface.
How do you create a subinterface on a Juniper router?
To configure subinterfaces on the distribution switch:
- On the trunk interface of the distribution switch, enable VLAN tagging:
- Bind vlan1’s VLAN ID to the logical interface:
- Set vlan1’s subinterface IP address:
- Bind vlan2’s VLAN ID to the logical interface:
- Set vlan2’s subinterface IP address:
How do you tag a VLAN in a juniper switch?
Associate a series of tagged VLANs when you configure an interface in one of two ways:
- Include the name of the series: [edit interfaces] [email protected]# set interfaces ge-0/0/22.0 family ethernet-switching vlan members employee.
- Include the VLAN range:
What is VLAN subinterface?
Ethernet interfaces support IP, PPPoE, MPLS, or both IP and PPPoE on each VLAN. In addition to a VLAN major interface level, a VLAN subinterface level distinguishes the VLAN. Tasks to configure VLAN subinterfaces are: Creating a VLAN Major Interface. Configuring IP over VLAN.
How do I turn off Juniper interface?
– To Juniper disable interface:
- [email protected]# set interfaces ge-0/0/1.0 disable << This is cisco equivalent of “shutdown” – To Juniper enable interface:
- [email protected]# delete interfaces ge-0/0/1.0 disable << This is cisco equivalent of “no shutdown” Verification:
- [email protected]#show ge-0/0/1.0.
What is Juniper default VLAN?
In Cisco switches the default VLAN is untagged and is the native VLAN i.e. VLAN 1 but in Juniper there is no default native VLAN. You must configure it manually. In Cisco switches the trunk ports accept all VLANs in the range of 1 to 4095 by default but in Juniper, trunk ports do not support any VLANs.
How do I enable VLAN tagging?
Enable or disable VLAN tagging
- Click Cluster Management > Network Configuration > External Network.
- Click View/Edit next to the subnet that you want to modify.
- Click Edit.
- Select the Allow VLAN Tagging checkbox to enable or disable VLAN tagging.
How do you set the trunk port on a Juniper switch?
- From configuration mode, create the VLAN and add access vlan members to it:
- Verify the VLAN and interface: root# run show vlans.
- Configure the trunk and add VLAN that was created in previous steps:
- Verify the trunk and the VLAN members for this trunk: root# run show interfaces ge-0/0/.0.
What are the benefits of using VLANs?
VLANs provide a number of advantages, such as ease of administration, confinement of broadcast domains, reduced broadcast traffic, and enforcement of security policies. VLANs provide the following advantages: VLANs enable logical grouping of end-stations that are physically dispersed on a network.
How to configure Ethernet ports for srx210?
The following procedure shows the default configuration for Ethernet switching on interfaces on a SRX210 device. The factory default configuration includes a predefined VLAN named vlan-trust and a VLAN interface named vlan.0 that is assigned to an IP address of 192.168.1.1/24 and as a Layer 3 interface.
What are the features of a juniper SRX router?
J Series routers include Ethernet switching features, integrated routing and bridging, and support for several Layer 2 protocols. These features are also present in branch SRX Series Services Gateways (SRX100, SRX110, SRX210, SRX220, SRX240, SRX550 and SRX650). Switching is not available (and not needed) on the high-end SRX devices.
How to configure Ethernet ports for switching juniper?
Specify a new VLAN, which will be used for switching, in this case vlan 100: Assign this VLAN interface as your Layer3 Interface on this VLAN: Configure a VLAN interface with an IP for this VLAN. (It must be on a different L3 subnet than the other VLANs.)
What are the features of the SRX Ethernet switch?
The SRX Series products provide a comprehensive suite of Ethernet switching functionality. Ethernet switching features eliminate the need for Layer 2 switches in small branch offices and act as an aggregate switch in medium-sized branch offices.
