Catalyst 2960-X and 2960-XR Switches Overview, Configuration, and Troubleshooting
Q: In that switch, are there only 8 ports with PoE?
A: Yes it support POE+ on first 8 ports.
Q: Can you use ISSU for firmware upgrading, with the dual CPU's ?
A: ISSU is for 4500 family of switches. 2960X supports stacking.
Q: Does 2960 support Some kind of wake on LAN in case it is in hybernation mode?
A: The Switch will be in hibernation mode until the configured time interval, once the time interval is over, it reboots.
Q: ??Q: Is there a bug, that 2960X stacks are not fully discovered in Prime Infrastructure 3.0 and 3.1?
Q: Is hibernation mode configurable or on by default?
A: Hibernation mode is configurable, not available on default.
Q: Does the switch have netflow lite built in feature?
A: Netflow lite is a feature configurable in 2960x.
Q: What routing protocols are supported?
A: RIP, OSPF, EIGRP are supported.
Q: When I have several hundred 2960X switches with 15.0(2)EX3 to EX5 (with the bug that it sometimes won't detect SFPs or FlexStack Plus modules), is the recommendation to power-cycle the switches for the upgrade to a fixed version like 15.0(2a)EX5 or 15.22E4)?
A: Yes, we need to power cycle the switch after upgrade to 15.2(2)E4 if the sfp is not detected.
Q: Is there a SW recommendation for 2960-S? If not, why not?
Q: What is the basis on which Broadcast itraffic via one link is sent over the other to avoid loop, any specific condition or rule?
A: No, it is similar to other switches when is related to the downlink ports. However if it is related to the broadcast package, one of the links of the stack has to be declared as a passive link so they don´t get looped in the network. (Keep in mind that the stack is connected as a ring).
Q: I understand this switches can do L3 routing, does it support NAT/PAT?
