A Cisco Systems Inc executive said on Wednesday that uncertainty still ruled over customers of the network equipment maker, and the outlook for future business conditions was still unclear.

He said it was hard to say whether conditions were now stabilizing or worsening due to poor visibility.

The world's biggest manufacturer of routers and switches is often seen as an early benchmark for global technology spending.

Cisco shares were up 82 cents or 5.7 percent at $15.21 in early afternoon trading, coming off their earlier peak of $15.35.

The company has forecast revenue in the current, fiscal third quarter to fall 15 percent to 20 percent from a year earlier.
