Chapter 1 Overview
Default Settings After Initial Switch Configuration
–
Configuration guidelines for Mediatrace and performance monitor:
Video monitoring is supported only on physical ports. It is not supported on EtherChannels.
When a switch receives excessive traffic, packets are dropped.
The switch supports policy maps and port-based trust only on ingress ports.
–
Limitations for Mediatrace and performance monitor:
You cannot configure video monitoring and a router or VLAN ACL on the same interface.
If you configure video monitoring before configuring the ACL, the ACL settings override the
video monitoring settings, and a message appears.
If you configure the ACL before configuring video monitoring, the switch rejects the video
monitoring commands, and a message appears.
As video monitoring packets pass through the network queues, they can be dropped.
The switch cannot apply QoS settings to packets forwarded in software.
The switch cannot match lost or dropped packets to a specific traffic or data flow. For
information about these packets, see the ingress and egress QoS counters.
Default Settings After Initial Switch Configuration
The switch is designed for plug-and-play operation, requiring only that you assign basic IP information
to the switch and connect it to the other devices in your network. If you have specific network needs,
you can change the interface-specific and system- and stack-wide settings.
Note
For information about assigning an IP address by using the browser-based Express Setup program, see
the getting started guide. For information about assigning an IP address by using the CLI-based setup
program, see the hardware installation guide.
If you do not configure the switch at all, the switch operates with these default settings:
• Default switch IP address, subnet mask, and default gateway is 0.0.0.0. For more information, see
Chapter 1, “Assigning the Switch IP Address and Default Gateway,” and Chapter 1, “Configuring
DHCP Features and IP Source Guard.”
•
Default domain name is not configured. For more information, see Chapter 1, “Assigning the Switch
IP Address and Default Gateway.”
• DHCP client is enabled, the DHCP server is enabled (only if the device acting as a DHCP server is
configured and is enabled), and the DHCP relay agent is enabled (only if the device is acting as a
DHCP relay agent is configured and is enabled). For more information, see
Chapter 1, “Assigning
the Switch IP Address and Default Gateway,” and Chapter 1, “Configuring DHCP Features and IP
Source Guard.”
•
Switch stack is enabled (not configurable). For more information, see Chapter 1, “Managing Switch
Stacks.”
• Switch cluster is disabled. For more information about switch clusters, see Chapter 1, “Clustering
Switches,” and the Getting Started with Cisco Network Assistant , available on Cisco.com.
•
No passwords are defined. For more information, see Chapter 1, “Administering the Switch.”
• System name and prompt is Switch. For more information, see Chapter 1, “Administering the
Switch.”
•
NTP is enabled. For more information, see Chapter 1, “Administering the Switch.”
