How to Set Console Passwords on Huawei Switch? Can Access
Securing your Huawei Switch isn''t about ticking boxes—it''s about building a fortress. A console password is the first brick, but layered access control, rigorous auditing, and smart
Huawei Switch Access Layer Settings
Access layer configuration on Huawei switches involves VLAN assignment, port configuration, ACLs, port security, and Layer 2 management to ensure secure and efficient network access.VLAN ConfigurationVLANs segment a network into multiple broadcast domains. On Huawei switches, you can create VLANs and assign ports as follows:Enter system view: system-viewCreate VLANs: vlan batch 2 3 (creates VLAN 2 and 3)Assign a port to a VLAN in access mode:CodeCopyinterface ethernet 2/0/1port link-type accessport default vlan 2quit For trunk ports carrying multiple VLANs:CodeCopyinterface GigabitEthernet 0/0/1port link-type trunkport trunk allow-pass vlan 2 3quit This ensures hosts within a VLAN can communicate while isolating traffic between VLANs .Port Configuration and SecurityProper port configuration is critical for access layer security:Enable a port:CodeCopyinterface GigabitEthernet 0/0/1undo shutdown Apply port security to prevent unauthorized access:CodeCopyport-security enableport-security mac-address sticky Rate limiting can be applied to prevent traffic floods:CodeCopyqos lr outbound cir 100000 Always save configuration: save .Access Control Lists (ACLs)ACLs filter traffic based on source/destination IPs, ports, and protocols:Basic ACL: Filters IPv4 packets by source IP, fragment info, or time range.Advanced ACL: Filters by source/destination IP, protocol type, TCP/UDP ports, fragment info, and time range.Apply ACL to a service module or interface to allow or deny traffic:CodeCopyacl 3000rule permit ip source 192.168.1.0 0.0.0.255interface GigabitEthernet 0/0/1traffic-filter inbound acl 3000quit This ensures only authorized traffic reaches the access layer devices .Layer 2 ManagementLLDP: Enables discovery of neighboring devices and topology mapping:CodeCopylldp enable Configure LLDP intervals, delay, and hold time to optimize neighbor information updates .Eth-Trunk: For link aggregation and redundancy:CodeCopyinterface Eth-Trunk 1mode lacp-staticquit or dynamic mode:CodeCopymode lacp-dynamicquit Verification and MonitoringCheck VLANs: display vlanCheck interface status: display interface briefCheck ACLs: display acl allCheck LLDP neighbors: display lldp neighborCheck MAC and ARP tables: display mac-address, display arpView logs: display logbuffer . By combining VLAN segmentation, port security, ACLs, and Layer 2 management, Huawei access layer switches can provide secure, efficient, and manageable network access.
