OL-26675-02
Limitations and Restrictions
• The system cannot scale to greater than 512 SIP flows with MSP and metadata enabled.
Workaround: None. CSCty79236
• When sup1 is in ROMMON and sup2 is in IOS, only sup2 can read the SEEPROM contents of the
following chassis components:
–
chassis
–
fan-tray
–
clock-module
–
power-supplies
–
mux-buffer for each linecard slot
–
linecards
On sup1, when the sprom read .. command is entered for any of the above components, the
SEEPROM contents are displayed as all “0”s.
When sup1 and sup2 are both in ROMMON (or both in IOS (SSO state)), they can read all
SEEPROMs.
• On the following linecards running IOS XE Release 3.2.3:
–
10/100/1000BaseT Premium POE E Series WS-X4648-RJ45V+E ( JAE1348OY52)
–
4 Sup 7-E 10GE (SFP+), 1000BaseX (SFP) WS-X45-SUP7-E ( CAT1434L0G4)
the following restrictions apply:
–
Sub-interrfaces are not supported on 1 Gigabit and Ten-Gigabit interfaces.
–
Port-channel members do not support multiple classification criteria for a QoS policy.
–
CEF is disabled automatically when uRFP is enabled and TCAM is fully utilized.
• While configuring an IPv6 access-list, if you specify "hardware statistics" as the first statement in
v6 access-list mode (i.e. before issuing any other v6 ACE statement), it will not take effect.
Similarly, your "hardware statistics" configuration will be missing from the output of the show
running command.
Workaround: During IPv6 access-list configuration, configure at least one IPv6 ACE before the
"hardware statistics" statement. CSCuc53234
• Auto negotiation cannot be disabled on the Fa1 port. It must be set to auto/auto, or fixed speed with
duplex auto.
• When performing an ISSU between any releases prior to Cisco IOS 15.1(1)SG or 3.3.0SG to release
Cisco IOS 15.1(1)SG (or 3.3.0SG) or higher, a switch performing multicast routing may persistently
drop traffic after the upgrade completes. You can recover multicast traffic by reloading the chassis.
Alternately, you can remove all multicast configuration prior to ISSU, and add it back when ISSU
completes. CSCuj42672
