What is a link aggregation group Cisco?
What is a link aggregation group Cisco?
Link aggregation (LAG) is a partial implementation of the 802.3ad port aggregation standard. It bundles all of the controller’s distribution system ports into a single 802.3ad port channel. When LAG is enabled, the system dynamically manages port redundancy and load balances access points transparently to the user.
What is a requirement for link aggregation?
Link aggregation only combines multiple physical NICs but in a non-global zone all interfaces are virtual. Therefore, you cannot create a link aggregation from the non-global zone. All the datalinks in the aggregation must run at the same speed and in full-duplex mode.
How does link aggregation work?
Link aggregation is a way of bundling a bunch of individual (Ethernet) links together so they act like a single logical link. Another important reason for using link aggregation is to provide fast and transparent recovery in case one of the individual links fails.
What devices are capable of link aggregation?
Link aggregation lets you combine multiple Ethernet links into a single logical link between two network devices. The most common combinations involve connecting a switch to another switch, a server, a network attached storage (NAS) device, or a multiport WiFi access point.
What is static link aggregation?
Static link aggregation is a method of combining or bundling of multiple switch ports or nics to form a single etherchannel. It increases throughput and redundancy for the two connecting devices. A static link aggregation means that you manually configure the links you wish to use as part of your etherchannel.
How to configure Link Aggregation (LAG) settings?
Log in to the web configuration utility and choose Port Management > Link Aggregation > LAG Settings. The LAG Settings page opens: Step 2. Click the radio button of the LAG you want to edit. Step 3. Click Edit to configure the LAG. The Edit LAG Settings window appears. Step 4. (Optional) From the LAG drop-down list choose a LAG to configure.
How to configure lag management for the SF/SG 200/300 series switches?
• SF/SG 200 and SF/SG 300 Series Managed Switches Step 1. Log in to the web configuration utility and choose Port Management > Link Aggregation > LAG Management. The LAG Management page opens: Step 2. Click the respective radio button of the desired algorithm in the Load Balance Algorithm field.
What is linklink aggregation Control Protocol LACP?
Link Aggregation Control Protocol (LACP) is used to prioritize ports on a LAG. A dynamic LAG can have up to 16 ports of the same type but only 8 can be active at one time. When a LAG has more than 8 ports, the switch uses LACP port priority to determine which ports will become active.
How do I protect the lag through an uplink?
(Optional) Check Enable in the Protected LAG field to protect the LAG through an uplink. This makes the LAG a protected port for layer 2 isolation between interfaces that share the same VLAN. A protected port does not forward any traffic to any other protected port on the same switch.
