A network administrator needs to establish out-of-band administrative access to a Cisco Wireless LAN Controller (WLC) for system maintenance. The out-of-band management network uses subnet , which is completely isolated from production wireless client traffic and general infrastructure VLANs. Which physical interface and configuration method on the WLC should the administrator use to achieve this isolated management connection?
- Configure the physical Service Port with an IP address on the subnet, as it provides dedicated out-of-band management access and maintains a separate routing table.Cevap
- BAssign the primary Management Interface to the subnet while enabling PortFast on the switch trunk port connected to the distribution system.
- CMap the Virtual Interface to VLAN 100 on the upstream switchport and match the native VLAN ID on the connecting trunk link.
- DAssign a Dynamic Interface to the network and rely on LLDP TLV neighbor information to route administrative SSH and HTTPS traffic.
Cevap
The Service Port should be configured with an IP address on the out-of-band network because it is physically isolated and maintains a distinct routing table from the main distribution system ports.
The Cisco WLC Service Port is specifically designed for out-of-band management. It operates independently from the controller's distribution system ports and maintains its own routing table, allowing network administrators to access the WLC GUI, SSH, or SNMP even if the production network or in-band interfaces are unreachable.
