ExtremeXOS 12.4.1 Release Notes
73
PD3-166858162 On a Summit X250e-24x switch, if one of the combo ports is redundant to a front panel
port, after rebooting, the second combo port does not come up if the primary port for the
SRP is active.
PD4-375560851 When configuring or unconfiguring a mirroring loopback port, the user may notice several
unexpected port state transitions on a Summit X650 switch.
ACL
PD3-77983510 Summit X450a and Summit X450e series switches and BlackDiamond 8800 a-series and
e-series modules provide more powerful ACL capabilities. Because of this, the amount
and complexity of ACL rules will naturally impact the time needed to process and apply
the ACL rules to the switch. This will also impact switch bootup time. Access Control List
limitations fall into two areas: physical and virtual.
Physical Limits—Summit X450a and Summit X450e series switches:
The per-VLAN, wildcard (port any), and single-port access list installation limitations are
1,024 rules for the Summit X450e and 2048 rules for the Summit X450a.
Physical Limits—BlackDiamond 8800 a-series and e-series modules:
The per-VLAN, wildcard (port any), and single-port access list installation limitations are
1,024 rules for the e-series modules, and 2048 rules for the a-series modules.
Extreme Networks recommends that you configure ACLs as per-VLAN, wildcard, or single-
port. If either of the following is true, you will have to configure ACLs with multi-port
lists:
Your application requires that ports do not have a homogeneous ACL policy.
When BlackDiamond 8800 original series modules are operational in the same chassis, it
may be necessary to configure ACLs to specific port-lists instead of as wildcard or per-
VLAN. This is because the original series modules have smaller physical limits.
Virtual Limits—Summit X450a and Summit X450e series switches:
When configuring a multi-port ACL, use the following guideline. The total ACL count (as
calculated by ACL rules times ports applied to) should not exceed 48,000 total ACL
rules.
For example, applying a 1,000 rule policy file to a 48 port multi-port list is supported
(1,000 rules * 48 ports in the list <= 48,000).
Virtual Limits—BlackDiamond 8800 a-series and e-series modules:
When configuring a multi-port ACL, use the following guideline. For any a-series or e-
series blade in the system, its total ACL count (as calculated by ACL rules times ports
applied to) should not exceed 48,000 total ACL rules.
For example, applying a 1,000 rule policy file to a 48 port multi-port list on an a-series
module on slot 1 and an e-series module in slot 2 is fine. Neither module exceeds the
48,000 total ACL rules.
Excessive boot times and CPU resource starvation can be seen with larger total rule
counts. If your application requires additional capacity, contact Extreme Networks.
ESRP
PD4-464792522 A load-shared port in a host attach configuration is deleted without warning or error when
sharing is disabled on the port.
MPLS
PD4-822663105 Uploading or downloading a configuration results in an MPLS configuration being lost as
MPLS is not deleted from the VR-Default.
