You can set QoS parameters in the IP packet header to notify a network node of QoS requirements.

Each device along the transmission path obtains the service requirements type of packets by analyzing the IP packet header.

When administrators configure Free Mobility, they need to select proper authentication points and policy execution points.

In the Free Mobility, Administrators can add static network segments or server resources to security groups, and manually bind their IP addresses to the security groups.

Free Mobility uses a configuration matrix to define access permissions between two security groups such as users and servers.

Free Mobility defines higher forwarding priorities for the VIP user group to ensure their network experience.

The switch uses the directly-connected interface to set up a TCP connection.

The switch's peer LDP ID is an interface IP address of the peer device.

The switch's peer LDP ID is the MPLS LSR ID of the peer device.

The switch uses the LSR ID to set up a TCP connection.

The Agile Controller uniformly deploys permission policies for controlling server access from personnel in each department. The administrator needs to focus on access permissions between departments. A key device in the campus can function as the policy execution point. After the deployment is complete, users can obtain access permissions no matter where they are and what access mode is used.

Policies are deployed automatically to control access between outsourcing personnel and

employees by policies and IP addresses, while ensuring correct the network access permissions of each user. It can also control data sharing among team members to guarantee enterprise data security.

When gateway resources are limited, automatic gateway selection and preferential forwarding of packets from VIP users guarantee fine network experience of VIP users.

The Agile Controller can automatically identify office requirements of working staff, without the need for manual configurations. Users can obtain network access permissions anytime, anywhere.

LSPs are classified into static and dynamic LSPs. A static LSP is manually configured by an administrator. Adynamic LSP is dynamically established using routing and label distribution protocols.

When labels are allocated manually, ensure that the outgoing label of an upstream node is the same as the incoming label of the downstream node.

LSPs created by static Distribution labels can be dynamically adjusted according to network topology changes, without the need for administrator intervention.

Dynamic LSPs are established using label distribution protocols, such as MP-BGP, RSVP-TE, and LDP.

The DHCP snooping binding table contains dynamic binding entries and static binding entries.

DHCP snooping distinguishes the trusted interface and untrusted interfaces. Untrusted interfaces do not process DHCP Reply packets.

The static binding table is manually set on the inbound interface and the aging time is also manually set.

When DHCP snooping is used at Layer 2, the interface information also can be obtained for the binding table if the Option 82 function is not configured.

ASPF monitors packets during communication.

ASPF dynamically creates and deletes filtering rules.

ASPF uses the Servermap table to dynamically allow data of multi-channel protocols through.

The five-tuple Server-map entry implements a similar function to the session table.

After receiving a data packet, the ingress node searches for tunnel ID in the ILM table first.

The ingress node finds the NHLFE entry matching the tunnel ID in the ILM table to associate LFIB and NHLFE entries.

The ingress node checks the NHLFE entry to obtain the outbound interface, next hop, outgoing label, and label operation type. D. The label operation type is Push.

The ingress node adds the obtained label to the IP packet, processes EXP by QoS policy, processes the TTL, and forwards the encapsulated MPLS packet to the next hop.

LDP discovery mechanisms include the basic discovery mechanism and extended discovery mechanism.

The LDP basic discovery mechanism discovers directly-connected LDP peers on a link.

The LDP extended discovery mechanism discovers indirectly-connected LDP peers.

LDP discovery mechanisms need to specify LDP Peer.

Multiple virtual routers can be configured on an interface of a router so that the router functions as the master of the virtual router and the backup of another virtual router.

In load balancing mode, multiple routers transmit service at the same time, so at least two or more virtual routers are required.

In load balancing mode, two or more VRRP groups are created, and multiple routers transmit services.

During priority configuration, the VRRP master of the three virtual routers can be on different routers.

During traffic control, CAR enables the device to discard the packets of which the rate is exceeded.

During traffic control, GTS enables the device to buffer packets of which the rate is exceeded into queues.

During traffic control, LR enables the device to discard the packets of which the rate is exceeded.

During traffic control, LR enables the device to buffer the packets of which the rate is exceeded and to send packets to QoS queues.

Packets with the same FEC are processed differently on a MPLS network.

FECs can be divided flexibly by source IP address, destination IP address, source port, destination port, protocol type, VPN, or any combinations of them.

MPLS classifies packets with the same forwarding processing mode into one FEC.

One FEC has only one unique label marker.
