summit200-48 ports

[Eh_Mohsenpouria]

hi,
i have a summit200-48,
1- i do factory reset using> unconfigre sw all
2- then i set ip address on Default vlan (172.16.100.1) now each computer that connected to any of 48 switch ports can ping valn ip(172.16.100.1).
3- now i make loop between 2 ports of switch for some seconds.
4- now ping is timed out.
5- now i remove loop then only computers connected to ports 1-24 can ping default vlan and 25-48 have timeout. in another way now i have 24port switch!
6- with reset everything is ok.

what happend?

This switch is end of everything (sale/support/life). Upgrade to the latest available ExtremeWare version, if that does not fix it replace with an X460 

A loop can cause some unpredictable issues on switches. Resetting the switch would resolve this issue. Disabling and enabling the ports may as well. My recommendation is not to loop the ports into each other.
