Viewing and Renaming Ethernet Flow Domains
Viewing and Renaming Ethernet Flow Domains
An Ethernet flow domain represents an Ethernet access domain. The Ethernet flow domain holds all
network elements between the CE (inclusive, if managed by the SP), up to the SP core (exclusive). This
includes CE, access, aggregation, and distribution network elements.
An Ethernet flow domain can have no N-PEs (flat VLAN) or one or more N-PEs (N-PE redundancy
configuration). The Ethernet flow domain is defined using physical connectivity at the port level, and
not at the network element level. STP is used to mark the root bridge, root or blocked ports, and blocked
VLAN links.
Security Properties Areas
Port Security Status of security on the port: Enabled or Disabled.
MAC Address Limit Maximum number of MAC addresses allowed on the interface.
Aging Type Type of aging used for automatically learned addresses on a secure port:
• Absolute—Times out the MAC address after the specified age-time
has been exceeded, regardless of the traffic pattern. This is the
default for any secured port, and the age-time value is set to 0.
• Inactivity—Times out the MAC address only after the specified
age-time of inactivity from the corresponding host has been
exceeded.
Aging Time Length of time, in minutes, that a MAC address can remain on the port
security table.
Violation Mode Action that occurs when a new device connects to a port or when a new
device connects to a port after the maximum number of devices are
connected:
• Protect—Drops packets with unknown source addresses until a
sufficient number of secure MAC addresses are removed to drop
below the maximum value
• Restrict—Drops packets with unknown source addresses until a
sufficient number of secure MAC addresses are removed to drop
below the maximum value and causes the Security Violation counter
to increment.
• Shutdown—Puts the interface into the error-disabled state
immediately and sends an SNMP trap notification.
