Course ContentLayer 2 Switching
Notes:
What is Juniper ELS? "Enhanced Layer 2 Software (ELS) provides a uniform CLI for configuring and monitoring Layer 2 features on QFX Series switches, EX Series switches, and other Juniper Networks devices, such as MX Series routers. With ELS, you configure Layer 2 features in the same way on all these Juniper Networks devices."

1. EX Series Ethernet Switches use Link Layer Discovery Protocol (LLDP) and Link Layer Discovery Protocol–Media Endpoint Discovery (LLDP-MED) to learn and distribute device information on network links. 2.ELS CLI handles default Vlans to standard JUNos CLI Some switches running Junos OS that do not support the ELS configuration style are preconfigured with a VLAN named default that does not tag packets and operates only with untagged packets. On these switches, each interface already belongs to the VLAN named default and all traffic uses this VLAN until you configure more VLANs and assign traffic to those VLANs. 4. On a switch that runs Junos OS that does not support ELS, a trunk port does not recognize packets that do not include VLAN tags, which are also known an untagged packets. On a switch that runs Junos OS that supports ELS, a trunk port recognizes untagged control packets, but it does not recognize untagged data packets 3. For a simple network that has only a single VLAN, all packets include a default 802.1Q tag, which is the only VLAN membership that does not mark the packet as tagged. 4. Giving a default vlan a tag will mean it is tagged on the trunk, tried and tested in the lab. -------------------------------------------------------- Bridging & VLANs (including Native and Default) Link Link Layer Discovery Protocol–Media Endpoint Discovery (LLDP-MED) Link Using LLDP-MED to deliver Voice VLAN Link Example: Configuring BA Classifiers Link Bridging and VLAN's Link Q-in-Q Tunneling Link Configuring Q-in-Q Juniper Link Spanning Tree
Notes:
1 Default port priority = 128 port numbering starts at 513 2. Default Bridge Priority starts at 32768 3. to activate rstp use "activate protocols rstp" then assign to each port [edit protocols rstp] set int ge-0/0/1 To force stp use "force version" Port Security
