Documentation Updates for Software Release4.2
Documentation Updates for Software Release4.2
This section describes caveats for the Catalyst5000 family software release4.2 documentation. These
changes will be included in the next update to the documentation.
In the Catalyst 5000 Series Software Configuration Guide, on page 5-2 of Chapter 5, “Configuring
VLAN Trunks on Fast Ethernet and Gigabit Ethernet Ports,” the second paragraph of the
“Understanding How VLAN Trunks Work” section states:
“Fast Ethernet VLAN trunks use Cisco’s ISL or industry-standard IEEE802.1Q encapsulation to
carry traffic for multiple VLANs over a single link. Gigabit Ethernet trunks use only ISL
encapsulation.”
This section should state:
“Fast Ethernet and Gigabit Ethernet VLAN trunks use Cisco’s ISL or industry-standard
IEEE802.1Q encapsulation to carry traffic for multiple VLANs over a single link.”
In the Catalyst 5000 Series Software Configuration Guide, on page 5-10 of Chapter 5, “Configuring
VLAN Trunks on Fast Ethernet and Gigabit Ethernet Ports,” the third paragraph of the “IEEE
802.1Q Trunk Configuration Example” section states:
“To properly configure an IEEE 802.1Q trunk in software release 4.1, the trunk type
(encapsulation), trunk mode, and native VLAN must be the same on both ends of the link.”
This statement is correct. However, the native VLAN restriction applies not just to software
release4.1 but to all subsequent software releases, including software release 4.2. When you
configure an IEEE802.1Q trunk, the native VLAN must be the same on both ends of the trunk link.
The August 1998 Catalyst 5000 Series Module Installation Guide has incorrect information
regarding the availability of Gigabit Interface Converters (GBICs). There is no 1000BASE-LX
GBIC.
Instead, Cisco is shipping the 1000BASE-LX/LH GBIC (WS-G5486), in addition to the
1000BASE-SX GBIC (WS-G5484). The Cisco 1000BASE-LX/LH interfaces fully comply with the
IEEE 802.3z 1000BASE-LX standard, and their higher optical quality allows them to reach 10km
over single-mode fiber (SMF) versus the 5 km specified in the standard.
The August 1998 Catalyst 5000 Series Module Installation Guide has incorrect information
regarding the availability of the 10/100BASE-T Telco Ethernet switching module (WS-X5227P).
This module is not yet available.
Documentation Updates for Software Release4.1
This section describes caveats for the Catalyst5000 family software release4.1 documentation. These
changes will be included in the next update to the documentation.
In the Catalyst 5000 Series Command Reference publication, the set spantree portvlancost
command section has been updated. The cost parameter should have the following definition:
cost cost (Optional) Keyword that indicates the path cost. The portvlancost applies only
to trunk ports.
