Appendix B - Glossary
LAN:
Local area network
MAC address:
Media Access Control address - hardware identifier
Modbus/TCP: A Modbus protocol over Ethernet
MSTI: Multiple Spanning Tree Instance, sometimes written “MST instance”
MSTP: Multiple Spanning Tree Protocol
Multicast: communicating one-to-many
NIC: Network Interface Card
NTP: Network Time Protocol
Octet: Eight bits
Packet: A single unit of data received and transmitted by a router
PVID:
Per-VLAN identifier
QoS:
Quality of Service
Real-time ring: Proprietary redundancy protocol
RMON: Remote network monitoring
Root bridge: In STP and RSTP, bridge with the smallest Bridge ID
Root port: The port on a switch facing the root bridge.
RSA: The RSA fingerprint for the managed Switch’s encryption key is: 1e:0f:31:39:26:3f:23:
8c:ba:7e:e9:d1:56:ff:98:f6
RSTP: Rapid Spanning Tree Protocol
RSTP terms:
• Discarding = In this state, station location information is not added to the Filtering Database
(MAC table) because any changes in port role will make the Filtering Database
information inaccurate.
• Learnin g = In this state, information is being added to the Filtering Database under the
assumption that the port role is not changing. Gathering information before frame
relay (forwarding state) will reduce the number of frames sent out when entering the
forwarding state.
• Forwarding = Frames will be forwarded to and from the particular port that is in the forwarding
state. In addition, during the forwarding state, the learning process is still
incorporating station information
RSTP recovery time: Time to start forwarding messages on the backup port.
SAD: Security association database
SFP: Small form-factor pluggable
SNMP: Simple Network Management Protocol
SPD: Security policy database
SQE: Signal Quality Error
SSH: Secure Shell protocol
