Solaris tip of the week: Link Aggregation and Logical Interfaces

This tip describes two options for configuring network interfaces: 1) Link aggregation (IEEE 802.3ad), which uses Ethernet network cables/ports in parallel to increase the link speed above the limit of any single cable or port and increases redundancy for higher availability, and 2) Logical interfaces, which enable you to assign multiple IP addresses to a single physical interface and share the bandwidth of a single interface across multiple IP addresses.

Solaris link aggregation not working as expected

Hi, This is Solaris-10 x86 platform. I am not able to ping gateway associated with aggr50001. I am not getting idea, where could be issue. Please advise. # netstat -nr Routing Table: IPv4 Destination Gateway Flags Ref Use Interface --------------------...

NAME

       VLAN - virtual local area network

DESCRIPTION

       This manpage provides a brief overview of VLAN (virtual LAN) technology.

       VLANs  are logical, or network segments that can span multiple physical network segments.  A primary benefit of VLANs is that they can iso-
       late broadcast and multicast traffic by determining which destinations should receive that traffic, thereby making better use of switch and
       end-station resources.

       Logical	separation  using  VLAN allows for the logical grouping of PCs, servers and other network resources to behave as if they were con-
       nected to the same, physical segment, even if they are not.

       HP-UX VLAN is an implementation of IEEE 802.1p/Q standards.

       VLAN interfaces can be configured in HP-UX servers using the command (see nwmgr_vlan(1M)) or (see lanadmin_vlan(1M)).  HP  recommends  that
       you  use  for  HP-UX Release 11i Version 3 and forward.	Interfaces can also be configured using the web-based management tool HP-UX System
       Management Homepage (HP SMH).

       Each VLAN interface created is assigned a VLAN PPA (VPPA) that is unique across the system and a VLAN ID, that identifies the  virtual  LAN
       it is part of.  The VLAN ID is unique on the interface on which the VLAN interface is created.

WARNINGS

       The  and  commands are deprecated.  These commands will be removed in a future HP-UX release.  HP recommends the use of replacement command
       nwmgr(1M) to perform all network interface-related tasks.
