– 363 –
■
System Capabilities – The system capabilities identifies the primary
function(s) of the system and whether or not these primary functions are
enabled. The information advertised by this TLV is described in IEEE
802.1AB.
■
System Description – The system description is taken from the sysDescr
object in RFC 3418, which includes the full name and version identification
of the system's hardware type, software operating system, and networking
software.
■
System Name – The system name is taken from the sysName object in
RFC 3418, which contains the system’s administratively assigned name. To
configure the system name, see “Displaying System Information” on
page 66.
◆ 802.1 Organizationally Specific TLVs – Configures IEEE 802.1 information
included in the TLV field of advertised messages.
■
Protocol Identity – The protocols that are accessible through this interface
(see “Protocol VLANs” on page 154).
■
VLAN ID – The port’s default VLAN identifier (PVID) indicates the VLAN with
which untagged or priority-tagged frames are associated (see “IEEE 802.1Q
VLANs” on page 135).
■
VLAN Name – The name of all VLANs to which this interface has been
assigned (see “IEEE 802.1Q VLANs” on page 135.
■
Port and Protocol VLAN ID – The port-based protocol VLANs configured
on this interface (see “IEEE 802.1Q VLANs” on page 135.
◆ 802.3 Organizationally Specific TLVs – Configures IEEE 802.3 information
included in the TLV field of advertised messages.
■
Link Aggregation – The link aggregation capabilities, aggregation status
of the link, and the IEEE 802.3 aggregated port identifier if this interface is
currently a link aggregation member.
■
Max Frame Size – The maximum frame size. (See “Configuring Support for
Jumbo Frames” on page 68 for information on configuring the maximum
frame size for this switch.
■
MAC/PHY Configuration/Status – The MAC/PHY configuration and status
which includes information about auto-negotiation support/capabilities,
and operational Multistation Access Unit (MAU) type.
■
PoE – Power-over-Ethernet capabilities, including whether or not PoE is
