Study Notes
VLAN Frame Handling on Trunk Ports
- Trunk ports send data frames
- If the VLAN ID matches the port's PVID (Port VLAN ID) and is allowed by the port, the tag is removed, and the frame is sent
- If the VLAN ID differs from the PVID, the frame is not dropped but forwarded.
- The tag is stripped and the frame is forwarded.
VLAN ID Bit Length
- A VLAN ID is 12 bits long in the IEEE 802.1Q format.
802.1Q Tag Details
- TPID (Tag Protocol Identifier): Identifies the frame type, 0x8100 for IEEE 802.1Q frames
- PRI (Priority): Indicates the frame priority used for QoS (Quality of Service)
- CFI (Canonical Format Indicator): Indicates whether the MAC address is in canonical format. For Ethernet, it's 0.
- VLAN ID: Identifies the VLAN to which a frame belongs.
Host MAC Address on Switch
- The MAC address of host B corresponds to interface Eth-Trunk 1 on switch A
Designated Ports on Root Bridge
- All ports on the root bridge are designated ports
Designated Port Function
- A designated port forwards Bridge Protocol Data Units (BPDU) to the downstream switching device
- The device that owns the designated port is the designated bridge on that network segment
Bridge ID Unlikely to Appear
- Bridge ID 2048 00-01-02-03-04-CC is not likely to be seen
VLAN Creation using Batch Commands
- "vlan batch 10 20" creates VLANs 10 and 20
- "vlan batch 10 to 20" also creates VLANs 10 and 20
Root Bridge in STP (Spanning Tree Protocol)
- A root bridge's default path cost in STP is 0.
Network Access Restrictions
- An ACL (Access Control List) rule can filter network traffic to restrict host access to the internet during specific hours. This rule is applied to the traffic/filter outbound in the Go/0/1 interface allocation
Network Access Restrictions (ACL Rule)
- An administrative rule (ACL) to restrict host access to the internet between 8:00 and 17:00 on all days needs an ACL rule that denies access during those times via the Go/0/1 interface allocation
Incorrect ACL Rule
- A rule denying traffic from 200.0.12.0 to 200.0.12.7 prevents hosts with those IP adresses, including 200.0.12.8 from accessing the internet
SNMP Packets Sent by Device
- The managed device sends Get-Next-Request, and Response packets to the network management system (NMS).
Output Interface for VLAN Communication
- Inter-VLAN communication through single arm routing needs configuration on the G0/0/1 interface of the RTA
Network Device Planes
- A network device has control, data, and management planes
OSPF Network Types
- OSPF can operate on point-to-point, broadcast, and non-broadcast multiple-access network types
RSTP Convergence Speed
- Edge Port introduction and fast switching of root ports are factors that improve STP convergence speed.
IPv4 Packet Header Length
- 60B is not a possible IPv4 Packet header length.
OSPF DR and BDR Roles
- The router with the highest router ID is elected as the DR; the router with the second highest router ID is the BDR
VLAN ID Usage on Trunk Port
- A trunk port can convey VLAN tagged or untagged frames.
- In the case of a trunk port, a frame with the same VLAN ID as the interface PVID will have the tag stripped and forwarded. A frame with a differing VLAN ID will be forwarded with the tag.
