Chapter 8 Configuring VLANs on the ML-Series Card

Configuring IEEE 802.1Q VLAN Encapsulation

ML-Series switching supports up to 254 VLAN subinterfaces per interface. A maximum of 255 logical VLANs can be bridged per card (limited by the number of bridge-groups). Each VLAN subinterface can be configured for any VLAN ID in the full 1 to 4095 range. Figure 8-1shows a network topology in which two VLANs span two ONS 15310-CLs with ML-Series cards.

Configuring IEEE 802.1Q VLAN Encapsulation

You can configure IEEE 802.1Q VLAN encapsulation on either type of ML-Series card interfaces, Ethernet or Packet over SONET/SDH (POS). VLAN encapsulation is not supported on POS interfaces configured with HDLC encapsulation.

The native VLAN is always VLAN ID 1 on ML-Series cards. Frames on the native VLAN are normally transmitted and received untagged. On an trunk port, all frames from VLANs other than the native VLAN are transmitted and received tagged.

To configure VLANs using IEEE 802.1Q VLAN encapsulation, perform the following procedure, beginning in global configuration mode:

 

 

 

 

Command

Purpose

 

 

 

 

Step 1

 

 

 

 

 

 

ML_Series(config)# bridge

Assigns a bridge group (VLAN) number and

 

 

 

 

bridge-group-number protocol type

define the appropriate spanning tree type.

 

 

 

Step 2

 

 

 

 

 

 

ML_Series(config)# interface type number

Enters interface configuration mode to configure

 

 

 

 

 

the interface.

 

 

 

Step 3

 

 

 

 

 

 

ML_Series(config)# interface type

Enters subinterface configuration mode to

 

 

 

 

number.subinterface-number

configure the subinterface.

 

 

 

Step 4

 

 

 

 

 

 

ML_Series(config-subif)# encap dot1q

Sets the encapsulation format on the VLAN to

 

 

 

 

vlan-id

IEEE 802.1Q.

 

 

 

Step 5

 

 

 

 

 

 

ML_Series(config-subif)# bridge-group

Assigns a network interface to a bridge group.

Cisco Systems has long been a leader in networking and telecommunications technology, and among its impressive lineup of products, the Cisco ONS 15310 series stands out as an essential solution for optical networking. This series includes models such as the ONS 15310-MA, ONS 15310-CL, and ONS 15310-CA, each designed to meet the diverse needs of service providers and enterprises seeking to enhance their optical transport networks.

The Cisco ONS 15310-MA is an advanced multi-service platform designed for metropolitan area networks. It facilitates the seamless transport of data, voice, and video over optical networks. One of its main features is its ability to support a variety of interfaces, including Ethernet, SONET/SDH, and Wavelength Division Multiplexing (WDM), allowing users to integrate multiple services into a single platform. Additionally, the ONS 15310-MA supports advanced traffic management and Quality of Service (QoS) features to prioritize critical applications and ensure consistent performance.

The ONS 15310-CL variant is tailored for more specific applications, providing enhanced capabilities aimed at delivering carrier-grade services. It features a robust architecture that accommodates high-capacity traffic without compromising reliability. This model emphasizes low power consumption and a compact design, making it suitable for deployment in space-constrained environments. The ONS 15310-CL also supports a wide range of optical interfaces, making it highly flexible for various network configurations.

In terms of technologies, the Cisco ONS 15310 series leverages Optical Transport Network (OTN) capabilities, providing high efficiency and greater bandwidth utilization. OTN technology enables efficient error correction and adds resilience to the network through its built-in protection mechanisms. Furthermore, the series supports seamless integration with existing IP/MPLS networks, creating a cohesive infrastructure as organizations evolve their networking requirements.

One of the defining characteristics of the ONS 15310 series is its focus on scalability. Network operators can start with a modest deployment and gradually expand capacity as demand grows. This adaptability is complemented by Cisco's comprehensive management and monitoring tools, providing operators with real-time insights into network performance and facilitating proactive management.
