Ladies and Gentlemen:

As legal counsel for Extreme Networks, Inc., a Delaware corporation (the
"Company"), we are rendering this opinion in connection with the registration
under the Securities Act of 1933, as amended, of up to 608,561 shares of the
Common Stock, $0.001 par value, of the Company which may be issued pursuant to
the exercise of options granted under the Optranet, Inc. 2000 Stock Option Plan
and assumed by the Company (the "Assumed Options") pursuant to a Voting and
Buyout Agreement dated as of March 17, 2000 (the "Voting and Buyout Agreement"),
by and among the Company and Optranet, Inc., a Delaware corporation.

We have examined all instruments, documents and records which we deemed relevant
and necessary for the basis of our opinion hereinafter expressed.  In such
examination, we have assumed the genuineness of all signatures and the
authenticity of all documents submitted to us as originals and the conformity to
the originals of all documents submitted to us as copies.  We are admitted to
practice only in the State of California and we express no opinion concerning
any law other than the law of the State of California, the corporation laws of
the State of Delaware and the federal law of the United States.  As to matters
of Delaware corporation law, we have based our opinion solely upon our
examination of such laws and the rules and regulations of the authorities
administering such laws, all as reported in standard, unofficial compilations.
We have not obtained opinions of counsel licensed to practice in jurisdictions
other than the State of California.

Based on such examination, we are of the opinion that the 608,561 shares of
Common Stock which may be issued upon the exercise of the Assumed Options are
duly authorized shares of the Company's Common Stock, and, when issued against
receipt of the consideration therefor in accordance with the provisions of the
Assumed Options and the Voting and Buyout Agreement, will be validly issued,
fully paid and nonassessable.  We hereby consent to the filing of this opinion
as an exhibit to the Registration Statement referred to above and the use of our
name wherever it appears in said Registration Statement.

Respectfully submitted,

/s/ GRAY CARY WARE & FREIDENRICH LLP
