6. Extreme Networks Configuration Hints
 | Updating Firmware in an EAPS Environment |
|---|---|
When updating firmware in an Extreme Networks EAPS environment, be sure to temporarily disable your AMS-IX port(s). TFTP file transfers may cause EAPS instabilities resulting in bogus traffic. This is likely to trip the port security on the AMS-IX switches, which may result in 10 minutes downtime. |
Most people who use Extreme equipment do not have problems with their AMS-IX connections, some do. We would appreciate feedback from people running Extreme equipment on how they configure their AMS-IX facing side.
6.1. L2 Configuration
The configuration fragment below shows how to configure an intermediate L2 switch, which is also part of an EAPS ring. Port 1 is connected to the AMS-IX switch. Ports 2 and 3 are in the ring. The router is somewhere in that ring, in the “amsix” VLAN.
create vlan "ring" configure vlan "ring" tag 1200 # VLAN-ID=0x4b0 Global Tag 3 configure vlan "ring" qosprofile "QP8" configure vlan "ring" add port 2 tagged configure vlan "ring" add port 3 tagged create vlan "amsix" configure vlan "amsix" tag 1700 # VLAN-ID=0x6a4 Global Tag 9 configure vlan "amsix" add port 1 untagged configure vlan "amsix" add port 2 tagged configure vlan "amsix" add port 3 tagged configure port 1 auto off speed 1000 duplex full configure port 2 auto off speed 1000 duplex full configure port 3 auto off speed 1000 duplex full disable edp port 1 disable igmp snooping disable igmp snooping with-proxy create eaps "ring-eaps" configure eaps "ring-eaps" mode transit configure eaps "ring-eaps" primary port 2 configure eaps "ring-eaps" secondary port 3 configure eaps "ring-eaps" add control vlan "ring" configure eaps "ring-eaps" add protect vlan "amsix" enable eaps "ring-eaps" |
6.2. L3 Configuration
The configuration fragment below shows the relevant configuration information for a L3-only device. As in the previous example, port 1 is connected to the AMS-IX and is configured in the “amsix” VLAN (untagged).
