Gigabit Switching Overview
by DougR on Oct.08, 2008, under Adtran, Ethernet, Extreme, General, Hardware, Juniper
As data rates increase in the Enterprise LAN 10/100 or Fast Ethernet is quickly being moved out and replaced with Gigbit switching. Some manufacturers and lines do not even offer a 10/100 product. Below is a quick overview of the Gigabit offerings available today from manufacturers Catalyst distributes.
Double your bandwidth for free with 802.3ad
by DougR on Sep.24, 2008, under Adtran, Best Practices, Ethernet, Extreme, General, Juniper
Increasing bandwidth is a constant battle faced by every IT department. What happens when a high capacity server is hitting the limits of a single Gigabit link. What happens when 10G is not an option, but 1G is not enough. Simply connecting another cable is not the answer. The result will be a total loss of the network or a nice workout for your spanning tree configuration. The answer comes from the 802.3ad specification, or Ling Aggregation, LAG for short.
Extreme Networks QoS
by DougR on Sep.18, 2008, under Best Practices, Ethernet, Extreme, Hardware
QoS is in higher demand as networks grow and complexity of traffic patterns increase. Large file transfers can clog networks. High Internet usage can bog down connections with useless traffic from social network sites or sites like YouTube. Properly configured QoS or Quality of Service, can help to remove the negative effect of traffic patterns. Extreme Networks is well known for excellent QoS. Deep queue buffers and robust algorithms can allow for 100 percent utilization of your data switches. Keep reading for a quick QoS configuration for Avaya (and other vendors) VoIP.

TFTP servers are integral to upgrades on many platforms. On the Avaya IP Office, many times the Manager program acts a TFTP server, but is limited in capacity. Here is a list of free TFTP servers that can help with file transfers via TFTP.
Let the 10G race begin
by DougR on May.23, 2008, under Extreme, Juniper
Both Extreme Networks and Juniper Networks now offer 10G products. Just over a year ago 10G was a bleeding edge technology that was available but not typically implemented. At Interop 2008 Extreme discussed it’s X650 series 10G-Base switch (product details). Recently Juniper also announced line rate 10G interface modules on it’s IDP 8200 (product details). This extends the offering of 10G into a more manageable solution.
